    This is nothing new. I have a Sprint PCS Phone (Samsung 3500, great phone!) and I wrote a little perl script which checks my IMAP mail. While doing that I found lots of resources at phone.com. They have example perl scripts included in their development tools which show you everything your phone gives away.

    (If there is interest in the IMAP mail checking script for HDML phones, let me know.)

    Scuse me? Why do so many people think that a cell phone is a good medium from which to browse the web? I think wireless is _awesome_ for things like monitoring and notification, but, really, most of those phones have like 10x20 screens.. I don't really think that's "browsing' Size.. Sure, you can get some stock quotes or something..

    Does anyone else wonder if the over-hyping of everything internet related will die down any time soon, and just become another information medium?

    Does anyone else PRAY for it every day? :P

    My experience with Sprint PCS and the 'Wireless Web':

    It costs a lot (at least when I used it) about 35 cents a minute, with a minute minimum. I would logon, schlep through the crappy four line text menus only to get to a 'this feature coming soon' message. 35 cents down the drain.

    It is almost unusable. Do you want to order a book from Amazon after going 19 levels deep in a text menu, typing your credit card number and address on a numeric keypad? gimme a break.

    The features you would want just aren't there. How about a user customizable 'home page'. Quick shortcuts to stock quotes, weather, news briefs, sports scores - nope, have to navigate the menu system to get anywhere. Usability testing - anyone, anyone?

    Spring PCS service just sucks period. At least in Chicago. My phone dropped nearly half the calls I made, and failed to ring on incoming calls more times than I care to count.

    Just avoid Sprint period. My terrible experience with them just makes me laugh at the irony of their TV adds. 'Crystal Clear'? Can't they be sued for outright lies?

  • cool, I'd like to take a look at that script. care to post it?

    Want to work at Transmeta? Hedgefund.net? Priceline?

  • You're OK as long as you don't have Sprint Wireless Web.

    Which I don't, thank God. I can't picture the web on my Palm, let alone the 4x12 character display on my cell phone. I don't surf the web with my land-line phone. Why would I with a cell phone? Let's leave data access to data devices.

    Ahh. Glad to have that off my chest. :-)

  • The only thing I ever use the SprintPCS WW for is to check my account balance and minutes used/left. This is a huge time saver, since it previously required me to talk to a dumbotron "customer care advocate" and wait on hold. Ick.

    On the other hand, the damn thing doesn't work half the time, giving all kinds of arcane errors.

    Sure, I once spent $3.50 browsing through amazon, but it would have taken me about $5.00 just to enter my address and credit card number. thanks but no thanks Sprint.

  • Looks like it's a good thing that I don't have a cell phone

    Um.. is it just me, or is this extremely short-sighted reasoning? While this article might mean that it's a good thing that you don't have a Spring PCS phone that you use to access web pages, I don't see how this remotely changes the usefulness of cell phones in general, and even of non-Sprint PCS phones and/or of Sprint PCS phones that aren't used to access the web. Nothing I've read about this so far in any way makes me any less glad that I own a PCS phone that's capable of receiving email, SMS and pages.

  • by Anonymous Coward on Friday March 10, 2000 @08:08PM (#1210830)

    And the only one that counts is "Microsoft". Yeah, it's probably a coincidence, but it does seem odd that this would happen just when MS is gearing up their new web-phone strategy. Their Spring holdings will lose some value, but not much, and to MS the affect on consumer thinking will be worth a billion or so dollars more. In the coming weeks, you can expect to see a lot more "freak malfunctions" in the telecom industry, all tending to convince people that the old tech doesn't work.

    If you ask me, it's a bit disgusting: Peoples' security is being compromised, just for the sake of helping somebody's marketing strategy. Oh, well, that's capitalism! Anything goes, as long as it makes a buck.

    Imagine if someone tries to hack your server using one of these accounts. You could give him/her a call, and congratulate them on trying...

  • > Do you want to order a book from Amazon after going 19 levels deep in a text menu, typing your credit card number and address on a numeric keypad? gimme a break.

    Am I the only one that ever purchased a book at amazon.com using a web phone?

    Well, the only reason I did it was so that I can tell my kids later in life I was one of the first :)

    Anyway, if you have an amazon account and you are stupid enough to have "one-click" ordering enabled, it actually works pretty easily.
  • Mind you, if they can do ANY form of hacking from a cel phone, they should be respected for that. Either that, or their sanity should be questioned.

  • And analog works in more places than digital. And when reception is bad, analog might cut in and out but still be understandable. Poor reception on digital breaks up into an unintelligible buzzing rasping noise, that often does not recover, unlike with analog. And what's with the tinyness of new phones? I see people constantly shifting microsized cell phones from ear to mouth to ear to mouth to ear to... There is such a thing as too small. I love my old Mot flip phone. Always works. When the company switched to these LGI pieces of crap, we had to swap 'em out 3 times cause some of them kept quietly going into 'roam mode' afterwhich no calls could be mace or received, until you rebooted the phone. Yeesh. It's just like a PC.
  • Has anyone written a gopher client for the PCS?? it would just plain kick ass
  • Who would have thought that cell phones also contributed to the revealing of personal info on the net? Web browsers allow cookies. They give out referrer fields, etc. Cell phones don't have the memory space for cookies. They aren't advanced enough for referrer fields and they don't run Windows. But giving out your PHONE NUMBER to anyone??? That's even worse, IMHO. Of course, you can't actually surf the web, yet. But in a few years, cell phones will go the way of the Palm Pilot, with color screens, and proper browsers. THEN anyone with a web page need only go through the server logs and get phone numbers to sell to telemarketers. Or maybe telemarketers might set up pages with popular content people might access from their phones...
  • Have you ever heard of Ameritech (i'm sure other Telco's offer similar offers) Privacy Manager? If you don't have Caller ID info sent, it'll make you record your voice (like when calling collect), and it'll ask if you'd like to accept the call from the person.

    My paranoid conspiracy theory: Sprint purposely is doing this so that they can offer similar services on their cell phones.
  • by Anonymous Coward
    I have a StarTAC dual band Sprint PCS phone with the web browser. Its totally useless. The whole service is designed to take as long as possible to use, and at 95cents a minute, its very costly. And you only have about 4 different sites that work anyway. I suspect most users, like me, played with it once, saw their first bill, and never used it again. I don't see much of a privacy threat from something that people never use.
  • AT&T declined to say whether it automatically gives out customers' phone numbers to the Web sites they browse. Spokesman Ken Woo would only say that ``it's not an issue'' because the company hasn't received any complaints.

    This is a small part of this article [sfgate.com], which went up Tuesday March 7, 2000. It's not an issue because they haven't recieved any complaints.

    Hmmm...Maybe the reason for this could be that the telephone owners don't know that its going on!! I doubt the phone flashes a little message that says, "I'm about to send your phone number to this web site. Do you wish to continue?". Also, this is relatively new news to most people.
  • Kinda weird, since just about every MS employee with a cell phone has an AT&T digital phone (MS employees get a small discount). No discounts for Sprint though.
  • Whose idea was it for the software on the cell phones to give unique ID numbers to the websites? There are two major problems with this:

    1. If you can find someone else's unique ID (easy because they used the phone number), you can get them in trouble by impersonating them to websites.

    2. Websites can track you without cookies - and this includes tracking across websites.

    No, Sprint needs to set up a proxy that gives a number unique to each website by which Sprint can track abusers.

    The SF Chronicle [sfgate.com] printed up a follow-up article [sfgate.com] the next day.

    In a nutshell:

    • Sprint says that they'll stop doing this.
    • AT&T says that they give user's phone numbers out, too. They're not especially interested in changing this.
    • Sprint claims that websites knowing your phone number "was 'a nonissue' in focus groups."


    They said that they have a agreement with websites that they won't use the phone number for telemarketing. I don't remember getting asked, do you?
  • The other good reason not to use a cell phone is it's inherent trackability. But this is less publicized.
  • ...is if it turned out they were transmitting both halves of the MIN/ESN pair, and thereby providing instant cloneability for anyone with access to the server logs.

    OTOH, I'm sure that will happen at some point soon anyway.

    I have and use Sprint PCS. And the phone I use the Denso Touchpoint, the phone used to launch these services in the US. I am extremely satisfied with the voice service. I rarely have a problem with signal getting through, and it's a dual-band phone, which means I can switch to analog if digital doesn't get through. Above all, I have been most impressed with the quality of calls. Back to the topic, I did manage to rack up more than $20 in the first month playing around with the web.

    The service can be extremely useful and useless at the same time. All depends on how you want to use the service because of the weakness of the software used to browse. I found it was awesome for 3 main uses. First is stock and news information. It was easy enough to use the phone get this information from CNN and Yahoo!. Second, I found that the Mapquest can be useful. Although it can be cumbersome to use, it could serve a purpose to get direction from zip code to zip code or from address to address. But what impressed me the most was Yahoo!'s personalized services. You can check your email from the phone and even get access to a web scheduler or something like that (didn't bother exploring it).

    Overall, the service is cool, until you consider the alternatives. It's a pain the ass to even log in considering you have to punch the buttons 16 times for an 8 letter login. I've also seen those RIM two-way pagers in action, and got damn can it do so much more so much faster. As much as people are screaming about the need for better screens and speed, until there is a way to input with something over than keypad these things will remain only toys.

    Thank you for pointing this out--not enough people are aware of it.

    What most folks don't seem to realize is that no new legislation or technology is required for a cell phone provider to get a fix on your location: *they already have this ability*. All they need to do is triangulate based on the relative signal strength received from two or more nearby towers.

    This happens all the time in "emergency" situations; the only reason it's not (yet) a big deal is because the technology is being used to rescue people in danger, rather than, say, to track down and silence thought-criminals.

    So far as you know.
  • The difference between a cell phone that can surf the web and one that doesn't is probably a $0.50 computer chip. If there's any difference at all. Sure it might not be the BEST idea. Sure there are probably better solutions down the road. But what's the problem if the carriers want to give you MORE capability with your existing hardware? Isn't that classic geek?

  • I complained to SprintPCS in February about this problem. If you'd like to hear about my saga and also run a script to test your phone for this privacy problem, see http://snafu.fooworld.org/~fubob/ hdmlprivacy.html [fooworld.org].
  • I certainly do not agree! Order a book using your cell-phone as a browser? I dont think you got the idea. (You shouldnt order from Amazon anyway, but thats a whole different thread). I find it very useful to get stock prices, sports scores and maybe news headlines if I am really bored. Thats what it was designed for, and I think it works great. Just my 35 cents...
  • It does not use triangulation algorithm. It uses some sort of hyperbolic curvature algorithm based on signal strength and the location of the cell you are currently in and can be done with only one base tranceiver station. Trust me I work with the elves!
  • Think of something like a Palm Pilot but a bit narrower. Microphone in the fold open cover, virtual keypad on the screen, a 800x400 pixel color display. Fast data rates via GPRS or EDGE.
    Trust me, its coming.....
  • Sprint PCS coverage sucks almost anywhere you go.
    Here is why: When Sprint set up they're network, they opted to go with CDMA. CDMA base stations can cost 2x to 5x what a typical GSM or D-AMPS base station does (albeit with a much better voice quality and a dubiously better capacity per cell).
    Sprint in their effort to roll out their network real fast, skimped on the amount of base stations they bought, thus stretching their cells out to the maximum limit (i.e. bad coverage) which in turn led to more dropped calls, especially when driving.

    If they would have gone GSM or good old D-AMPS they could have had far better coverage and more happier customers. So it was not the technology or engineers, but the marketers and operations folks.
  • by Anonymous Coward
    Isn't putting the phrase "Unique ID number" next to "privacy" a contradiction?

    You should never, never doubt what nobody is sure about.
  • If you were worried about Big Brother coming and putting a silenced bullet in your back, don't you think one of the last things you would consider is talking on a damn cell phone?

    Frankly, I don't give a crap what the gov't knows about me. Hell, if a team of spooks is working round the clock just to track everything I do, that's almost flattering. In any case, my life isn't interesting or dangerous enough to warrant investigation.
  • With lithium-ion batterys (which seem to be standard issue with new cell phones now), and the release of the Transmeta Crusoe(sp?) processor, we'll probably start seeing phones with more computational power and longer battery life. Combine this with the recent development of display that are smaller, higher resolution, and have lower power requirements, and you have the recipie for a pretty kickass combination of a cell phone and a PDA. Combine this with a built-in GPS receiver, and you have a device that can show you a map, show where you are on that map, and help guide you to your destination.

    Don't get all giddy yet. I have some concerns. Wireless carriers have a direct monitary incentive to compell you to use on-line services so they can get their 90 cents a minute. On-line services have an interest in having whatever personal information they can get through your patronage. I'm also sure there are several government agencies, commercial entities, etc, that would love to know where you are, where you're going, and who you're going to meet. The possibilities range from the most innocent (showing you a banner ad for someplace you're going to pass near, remember the Ericcson Banner Ad article a couple days ago?) to the most egregious (i.e., everything Big Brother wants to know, you give without even thinking about it). If I've thought about it, you can bet that smarter people with power and influence have thought about it too.

    You're probably thinking to yourself how far fetched this is. Is it that far-fetched? If a phone is giving up your phone number to every web site it visits, all someone needs to do is connect that phone number to whoever the owner is. The comment I'm replying to mentioned that Yahoo has a personal scheduler service on-line and accessible from web-browsing phones. If you're asking a site for directions from Point A to Point B, chances are, you're either at Point A, or will soon be at Point B. What better way to keep tabs on people's activities then to have their phone number associated with personal information you deposit in centralized computer systems? As is it now, you can already be somewhat tracked down by carrying your cell phone when it's turned on.

    I see two possibilities: A) Phones will become simply wireless phone that double as a decent portible web terminal with better displays and input options, or B) Phones will become a combination of a wireless phone and a powerful PDA as well as a great solution for mobile web browsing.

    Of course, solution A offers more profit and more power then option B. So naturally, which option do you think we'll get offered?

    I'm the person that runs the Uplink servers for AT&T. (Uplink = Phone.com phone gateway software)

    AT&T is doing it right. We don't use phone numbers for subscriber IDs.
    Thou I do tend to use phone numbers for my test phones.
    Phones never talk to any web site directly, they use a proxy agent.
    The IP that is logged shows the agent IP, not the cell phone.

    Alot of posts bashing sprint. Just some quick information about Sprint vs. AT&T Wireless.
    Sprint uses on their own network and charges per kilobyte of SMS traffic.
    AT&T has roaming agreements with other cdpd carriers. (Larger coverage area)
    AT&T also has an unlimited usage plan.

    As for the phones being usable. They are not over hyped.
    You can view html web sites, but hdml and wap/wml/wml+ sites are native to the phone. (No translation needed.)
    Some of the interesting things you can use them for, Email, Info services (news, stocks, sports scores, phone book, fax, games), customized apps (Server status, ping, traceroute, circuit testing...), e-commerce (flowers, food, movie tickets), and on and on..
    One of the hottest usages are for dispatch customers. Check your next delivery, pickup, work order, etc...
    At work we can access our Exchange server to read our email and view our calendars. (This is priceless in a large company.)

    Most configuration for phones are done with a personalized web site. You use your personal computers web browser too setup your Email, Bookmarks, Calendar (sync to your exchange, notes, schedule+, etc.)
    Hookup a special cable to your internet phone and make your laptop wireless.
    If you just want the one piece wireless solution, get a sierra wireless air card (pc card).

    You need to think of the internet phone as a PDA. Extend your office, have quick access to your information. The biggest mistake I see people do is try to replace their laptop.

    IMHO,

    -Brook Harty
    (All comments are my own and not the opinion of AT&T Wireless.)

    PS. Whats the largest IPO ever? AT&T Wireless.
  • M$ is using AT&T's cdpd service for its wireless needs.
  • Did I make any sense? Is what Is anything I said in the realm of possibility? Or am I just going completely Oliver Stoner?

  • First of all, this is like saying "SHOCKING!!! Oh my god, your computer gives away your IP address."

    Your phone number is like your IP address people! Welcome to reality. You call me, I use callerID and nail you, or I refuse to return your packets.

    On the wireless web, the phone number "airlink address" is your phone number.

    Its also nice not to have to enter a username/password on your phone, but to have a website identify you via your phone, and store your preferences.

    I hate this stOOOPID "shocking" privacy expose's. Some idiot learns how to print HTTP headers and thinks he's a friggin genius who discovered the New World.

  • Why suggest proprietary software when instead we could tout free software? gv/gs (what have you) has read any/all pdf's i've fed it. You can even get an addon to read encrypted pdfs.

    Personally I have a gripe with adobe for "expanding" postscript and the forcing people to pay (for everything but the reader that is). Adobe, You make so many great software packages, but Acrobat sucks. It is just glorified postscript (which i don't have a problem with), but it 1. It is not terribly stable here at work or at home [if it works for one of you out there, please no flames... It doesn't concern me if it works on your hardware, unless you are planning on giving said hardware to me (Which would be greatly appreciated...)] 2. Reminds me of windows (Again, if you disagree, piss off) and 3. it is ugly, especially when compared to ghostview.

  • I'll kill everything, and everyone in sight
  • When resources and connectivity is what you pay for, and not airtime(like flat rate fees for normal phones) what you can get is a mixed voice activated PDA/cell/thingy

    You speak into the phone, it transmits to a processing center, does the appropriate action, and sends you back data.

    Of course, this does nothing for privacy, but is loads faster when trying to, say, browse a map, or find a restaurant, etc.

    Why put any processing power into a cell phone when it is already a wireless device?

    -AS
  • exactly. If you're looking at signal strength as well as direction, you wouldn't need two antennae. You would simply use the direction of the signal combined with the distance given by whatever function you have for signal strength vs distance. This is probably of the type 1/x^2, with some correction for atmospheric conditions etc.

  • by Anonymous Coward
    This was reported by HackerNewsNetwork.com a few days ago. Apparently (according to hackernewnetwork.com) Sprint intends to change their policy. Check out the article [hackernews.com].
  • Couple of thoughts,

    1. If you can find someone else's unique ID (easy because they used the phone number), you can get them in trouble by impersonating them to websites.

    Isn't this sort of a major problem now? ie: Hemos., Signal.11, .Jesser

    2. Websites can track you without cookies - and this includes tracking across websites.
    No, Sprint needs to set up a proxy that gives a number unique to each website by which Sprint can track abuser

    True, but what would be Sprints motivation? They really don't care, there is not revenue impact either way, just more money thown into development. Sort of like all the rest of the bigger wireless and LD companies on the web. Coninuing to expand on legacy systems, with bad architecture because it's cheaper.

  • Isn't Mitnik banned from using cell phones? So, it must be possible!


    -----
  • Distance (well, not really, but lag) is allready calculated for GSM/PCS/PCN AFAIK.

    The deal is that with TDMA there are several 'slots' in a given 'channel' for handsets to communicate. What is happening is that there are (IIRC) 4 slots of about 20ms, and each handset grabs one and transmits during this window only. Now for the signals from potentially four handsets on a given 'channel' speaking with a base station from different distances to arrive at the correct time (with no overlap) the protocol *has* to take into account the speed of light which is not infinite, compute the lag, and ensure that the handsets broadcast that little bit earlier for everything to work.

    What this means is that the base station allready knows with great accuracy the distance of a handset from it. The rest is trivial I guess. They allready track cellphones that are switched on from cell to cell (so that they know how to route the calls), and while you are actually making a call they know your exact location - I wouldn't be surprised if there was a way for the base station to initiate a 'trace' without you having to make a call. That would simplify matters greatly for the powers that be :)

  • First, allow me to address the voice quality of Sprints "crystal clear" digital phone service. I'm a heavy phone user (1000+mins a month). I have the thing in my ear all day and Sprint is beyond poor when it comes to service droping...digital static (which sounds like I'm a pilot on crack using and airplane PA system) and poor service.

    If you're looking for a way to comunicate with clients, family and friends while on the go, I think you'll have better "crystal clear digital clarity" if you put your message on a wadded up spit ball and did a 'drive-by straw-spit' on their house.

    On a lighter side, I really had to laugh at the headline and it's use of the word "Leak": Sprint Web Phones Leak Users' Phone Numbers

    As if to imply: "those pesky little phone numbers wouldn't leak out onto every server log on the net if it wasn't for that hole on the bottom of the router." Perhaps if we tried asking the little dutch boy to come along and put his finger in the leak, we could prevent this leaking travesty from befauling inosent Sprint and it's happy users.

    It's a molicious attempt to make money from the tracking data on a conection that the user pays for at the expense of privacy, and it's wrong.

    Does Sprint et al use WAP (Wireless Application Protocol) to provide these services or do they use "straight" HTML??

    Furthermore, does WAP protocol enable giving out unique identifiers, or has this been surpassed at the wireless service provider level?? As much as I know, WAP services are always for a fee, so the WAP service provider has to be able to track customers usage. This is propably most relevant in a situation, where a third party WAP service provider provides its services directly to customers' phones.

    Anyway, I'm guessing here. Does anyone know these issues? -mjpk

  • I'd imagine most people's complaints about the current cumbersome wireless web interfaces would be solved if more handsets like the Nokia 9110 Communicator [nokia.com] were available. This thing is a phone and palm-top rolled into one, and is just about the same size as the Touchpoint. Now if we could get someone to manufacture handsets in this form-factor running something with the application support of the Palm OS, I could toss my Touchpoint and Palm V into the trash, or at least onto EBay. Remember that wireless web access on the phone is in its infancy, much better options will be available down the road. I do find fault with Sprint, however, for pushing this service as something for the general public. It's not even close to being ready for that, and what we'll end up with is a bunch of consumers in a couple of years that want nothing to do with wireless web because they remember how awful it was to use it on their tiny StarTAC display.
  • Mitnick's banned from using anything more than a solar powered calculator.

  • I'm not entirely convinced about the accuracy that they can get.

    let's say that you are 5 km from a base station of a particular cell. It would take 1.66 *10^-5 seconds for the signal to travel that distance. At a data rate of 9600 baud (which I seem to remember is what GSM can do) this is ~ 16% of the transmit time for a single bit. I woulndn't think that correction would be neccessary for lightspeed errors in TDMA.

    second, you would need very accurate timing equipment to get an accurate fix, and that would cost a lot of money which the companies don't really need to spend (unless you happen to be of a paranoid persuasion, and suspect govt involvement).

    third, a more elegant solution would be to build in a gap between transmissions from each handset on the channel. This gap would be determined by the maximum lag possible within that cell. This would not affect call quality noticeably, and would save on the timing gear.

    fourth, I don't know how accurately it is possible to get a directional fix on a cell phone from a single tower. Again, there is no need for the telco to engineer the ability to get a directional fix on the phone, so why spend the money.

    lastly, the base transmitter polls all the phones in the cell every now and again, depending on traffic levels, to keep the master record of what phone is in what cell up to date. This is analogous to "initiating a trace", as you called it.

    Sprint uses neither. Sprint currently has rolled out Phone.com's proprietary solution. Phone.com will has a WAP capable infrastructure in their 4.0 products. Their 3.1 browsers also support WML, but don't use the WAP stack to talk back to the proxy. The WAP protocol does not specifically say to send out the MSISDN (phone number), however for identification purposes, the MSISDN is nice to have. Please NOTE, Identification IS NOT the same as AUTHORIZATION. No one should assume the MSISDN number is secure, since anyone can fake it. WAP services are not always for a fee, in fact most of the ones I've mucked with don't even require registration. Okay... for those who say just send out a Unique ID but not MSISDN, this may be spec'd in a future version of WAP. Namely, they may use the phone's unique serial number to ID the device, and hence the user. Cookies support will also be added eventually. They're still debating whether to make them proxy stored cookies or device based cookies. the air-interface currently isn't very fast, and the amount of flash memory availabe on the current generation WAP phones isn't very much. I'd expect some of the proxy providers to support proxy stored cookies well ahead of the official WAP forum stand, since cookies have been the number 1 request. And yes, everything in WAP goes through a proxy, even Secure connections. It is assumed the Proxy is "trusted" in secure connections, and a WTLS connection made from proxy to phone and a seperate SSL connection from proxy to website. The proxy in theory has access to all your data, although the data should reside decrypted for a brief instant of time, its possible a bug in the proxy could allow access to the information. I'd worry about that more than this MSISDN issue. eduar09@hotmail.com

    The privacy thing is a bit worrisome, and Sprint should consider identifying a phone to the net using something other than its number. It's just too easy to abuse.

    However, that's just common sense and isn't the reason why I'm posting. What stikes me is that a lot of the posts here sound like they're written by people who just don't get it. Web phones are in their infancy - think back to the web in 1992, when every browser was incompatible with all the others and each new release broke pages which worked fine before. That's the way it is with web phones now.

    This is new technology, and still has a lot of rough edges as site designers learn how to work within the limitations of the devices. The content designers are going to get better, and the phones themselves are going to improve. The keyboards are always going to be small, as are the displays (although the resolution will improve). Complaining that a phone keypad isn't good for entering lots of text. Well, duh! We'll just have to find a better way, like speech recognition or maybe setting up shortcuts using a full size keyboard and loading them into the phone.

    The pricing model sucks right now, but remember the web at 2400bps with time metered usage. We didn't give up on it just because it wasn't perfect. In fact we loved it and the competition soon brought prices down. That's what's going to happen with web phones, and right now is the most fascinating part, seeing all the possibilities and being able to influence how it all turns out.

    I guess I'm just surprised to see people on Slashdot slagging off these devices just because they're new, unfamiliar and still a bit clunky. To those people, all I can suggest is that they stick with their nice comfortable rotary dial phone and leave all this new fangled stuff to us nerds who like that sort of thing.

    (No, I don't work for Sprint, but I do work with web phones, so maybe I'm biased.)
  • I didn't think you were biased at all. I thought what you said was very -insightful-, and me without moderator points.. *sigh*

  • If the phone cannot handle cookies, then the server would have to do something to remember your last page hit. Who wants to surf the net on such a little and underpowered device? Connection bandwidth iss low and the browser is like lynx on acid. I would rather tote along a pda or laptop.
  • And here was me expecting to get flamed into a pair of smoking boots. Nice to know there are other neophiles out there.
  • Heck, yeah! I've got one of the dual-band StarTacs, and I'm pretty happy with it and with Sprint so far (they could credit my account a little faster once they get my money). However, I like the small size of the phone, and I use the web for three things:
    1. Checking how many minutes I have left in the month
    2. Using MapQuest occasionally (just from zip code to zip code, so it's easy to enter)
    3. Using a CGI script I wrote to put /. headlines in HDML (let me know if anyone's interested in the location)
    That's it, and all of those can be used without logging in or extensive data entry. I think I sent an email from my yahoo account just once to say I did it. Summary: There is plenty of stuff you can use, and the sites are all coming on line now (still wish I could define a home page, though).
  • From what I understand, they fixed this problem last week. I saw it on ZDTV...Take it with the reliability that you credit to them as a news source...
  • SprintPCS web phones use the phone.com browser, which provides cookies by storing them on a gateway server.
  • This is a very extreme oversite don't you think? I hope someone is getting seriously fired over this.
  • What seems to be missing in the discussion here is how essential being able to identify the phone number of the handset is in order for "m-commerce" to work at all.

    Because Sprint is a non-GSM service that, like most American cellphone companies, focuses on contract accounts, any transactions generated by m-commerce on a Sprint handset are billed either to the contract or to a credit card entered on the handset.

    This will not be the model used in the future in the US nor indeed the rest of the world. The world's dominant cellphone standard is GSM, and a large portion of the world's GSM users (the quickest-growing segment) are pre-paid cards.

    There is *no* way to identify these customers other than their GSM number. Any m-commerce transactions generated from such a handset will have to be billed directly to the pre-paid SIM card; that's they way it's expected to work, and the only assurance vendors will have of being paid. That means identifying customers by phone number.
  • ...one who says: "This is old, and therefore good."

    and one who says: This is new, and therefore better."

    I have found a happy middle ground - I'm a furious "early adopter", but only for things that aren't mission critical. (e.g. I never run a .0 release for real work.)

    I am often surprised at the degree of xenophobia and Luddite-esque commentary on /. I think part of having perspective comes from having lived through evolutionary periods enough to see that what goes around comes around again later.

    Does anyone else think after years of decentralization and PC "freedom", the a web browser looks an awful lot like a 3279G block mode terminal with a server sitting in a closet somewhere that's not next to your desk?
  • Most of the handheld satellite telephony projects
    (See "RIP Iridium" elsewhere for more on one.) have provisions for squirting user location from either embedded GPS receivers or satellite triangulation up to the gateway in order to effectively accommodate country-specific access requirements or tariff structures.

    We know that people want to sell location-based services. (They're already threatening to with my SprintPCS Neopoint phone, which apparently has a GPS pod one can clip onto the side.)

    I can't imagine the satellite phone companies won't want to shovel this data around too.

    And just wait, ALL U.S. cellphone subscribers will eventually have user location information gathered on a per-call basis, because the U.S. gov't wants it for Enhanced cellular 911 services. My take is that the carrot for deployment of 911 location services is the ability to make money by selling you door-to-door routing on your cellphone.

    I'm not going to argue with any of this, but I have some comments to add.

    1. I have had very little in the way of stability problems in Windows, but I have seen some stability problems with the Linux reader; in particular, if I ran it from the command line with the name of an encrypted PDF file, it crashed every time, while if I started it without naming a file, then loaded the encrypted PDF, it worked fine. (Incidentally, this was the only reason I loaded the Acrobat Reader on my Linux box; at the time, 9 months or so ago, I had no other way to read the PDF under Linux.

    2. It does remind me of Windows, or at least, the Windows version of Acrobat.

    3. I've made this comment about Acrobat looking ugly on screen as well, in particular, in comparison with Microsoft Word. Acrobat uses anti-aliasing on the display of text, which is why all the text looks fuzzy in Acrobat. Time has shown that anti-aliasing on text, at normal text sizes (like you might use in the body of some sort of document), simply doesn't look good; it makes the text too hard to read. On the other hand, Acrobat doesn't use anti-aliasing on bitmaps that are displayed at anything other than their natural size (which is almost unavoidable, if you're using Acrobat in the most common way, to produce electronically-deliverable documents whose main target is print). As a result, such bitmaps tend to have missing or duplicated rows/columns of pixels that make them look quite irregular. MS Word, for all its shortcomings, gets this correct - it uses anti-aliasing for scaled graphics, but not for text.

    Uhhm, *cough* not true *cough*.

    The legislation is under a modification to the FCC
    E911 regulations, requiring cellular network operators
    to provide the location of a caller to the
    emergency services in case of an emergency call.
    The reason for this is that the percentage of
    E911 calls coming in via cell phones is on the
    up-and-up and since the landline telco provides
    location info during E911 calls, the logic follows
    that the cellular operators should too.

    There are several competing technologies for
    locating cellular users, and while your statement
    about signal strenght is true-ish, that sort of
    system is not very accurate, and is too complex
    to be used in the mass market, i.e. the cell ops
    are not tracking you right now, but are actively
    looking at technological solutions to be able to
    do so.

    No doubt the network ops will look for commercial
    opportunites for the data they will be able to
    collect, I certainly would not spend upwards of
    UKP100M on a UK-sized network w/o having some
    possibility of getting a return on it, and there
    will probably be a can-o-worms about who gets
    access to the data, and under what circumstances,
    but I'm still in favour of it since it will bring
    a shed load of useful location-based services.
  • A couple of things..

    o PDF, IIRC, is royalty-free, which IIARC is why Apple is using it (display PDF) instead of display postscript for OSX
    o The acroread for linux is actually pretty good for viewing and printing PDFs, and I think it has a superior interface to GhostView/PDF (when bookmarks and thumbnails are encoded, particularly). It also feels faster.

    Shit, I'd have more of a problem with PostScript, as Adobe still charges royalties/license fees for it (where it can)...
