Except there is no correlation between the cost of this new type of cell and traditional cells, since there is no silicon in these ones and the manufacturing process is completely different.
I don't want the FBI to pull a Kim Dotcom on me.
The GSMA has a list of all issued IMEI numbers, since they're the ones who issue them.
A more effective way is to use blacklists though. It only really makes a difference if all carriers in a country share the same lists. Even better if it is shared internationally.
You should also charge the parents of the criminals too, since they're the ones who gave birth to them. Without the parents there would be no criminal!
Also arrest the treasury, if they didn't issue all money, no one would steal it!
When I bought my phone it was locked to 850/2100MHz
I installed cyanogenmod and now I can select 900MHz so I can use other carriers. The hardware isn't usually locked down, its just software.
Of thieves will just put the stolen phones in metal boxes so they can't be tracked, or simply turn them off then sell them to international customers.
It's already illegal to change the IMEI number of a phone. It's not supposed to be able to be changed. If you remove the number from a phone, it won't be be able to register on the network anyway.
In USA it can give you 5 years in jail.
It's illegal just to possess hardware or software that is capable of doing it.
Why not just mandate the carriers participate in international IMEI black lists?
It doesn't stop the phone working, just means it can't connect to the network.
Still has the effect of lowering the value of a stolen phone.
So if it gets wet it doesn't stop working.
The rubber plugs are for the USB and headphone sockets.
When was the last time you saw an iPhone with a MicroSD card slot or replaceable battery?
If there was no MicroSD card, SIM card and no replaceable battery, there would be no need for the removable back cover, that tends to fall off every now and then after two years of use.
Head phones can be replaced with bluetooth, charging can be done wirelessly, plugs can be made water proof.
The mic, speaker and vol/power buttons are already waterproof.
All hard drives these days have firmware update software available.
I wouldn't be surprised if there is a way to update keyboard firmware via software, since that would make manufacturing/production testing easier.
There is a streamlined customs process when travelling between NZ and AUS. Last time I went to Sydney, I just walked through those machines that take a picture of you and scan your passport. Didn't even have to talk to anyone.
There already is one.
The phone already has a unique ID as well (that you aren't supposed to be able to change, and in some countries is illegal to do so because its used to black list stolen phones), called the IMEI number. The SIM card has an IMSI number.
... then you need to manage the passphrase. Then all someone needs to do is find your password and they can answer your phone calls, receive your text messages - like two-factor text codes
A sim card is more secure than passphrase, since no one gets told the private key stored inside it and its never transmitted anywhere, except when its initially programmed by the telco.
waterproof phones? My Motorola Defy is good and all, but those rubber plugs and the seal around the battery cover can only take 1M of water pressure.
