Well, the inevitable hacking of Apple's latest flavor of iPhone has happened. Named "purplera1n," the tool will only allow installation of unauthorized applications instead of a full unlock. "The purplera1n jailbreak will free your iPhone from the limitations imposed on it by AT&T and Apple. After jailbreaking, a user will be able to customize the iPhone with home-screen wallpapers and third-party ringtones. But the biggest advantage of jailbreaking is the support of unapproved apps such as iBlackList (blacklists and whitelists for contacts) and many others."

Tim O'Reilly wrote in Forbes a while back that he thinks the Kindle only has another two or three years of life left, unless Amazon wises up and embraces open standards. He came to this conclusion, in part, because of his experience deciding how to publish documents on the web back in the mid-1990s. "You see, I'd recently been approached by the folks at the Microsoft Network. They'd identified O'Reilly as an interesting specialty publisher, just the kind of target that they hoped would embrace the Microsoft Network (or MSN, as it came to be called). The offer was simple: Pay Microsoft a $50,000 fee plus a share of any revenue, and in return it would provide this great platform for publishing, with proprietary publishing tools and file formats that would restrict our content to users of the Microsoft platform. The only problem was we'd already embraced the alternative: We had downloaded free Web server software and published documents using an open standards format. That meant anyone could read them using a free browser. While MSN had better tools and interfaces than the primitive World Wide Web, it was clear to us that the Web's low barriers to entry would help it to evolve more quickly, would bring in more competition and innovation, and would eventually win the day."

An anonymous reader sends news that TerreStar-1, the largest satellite ever made for the purpose of telecommunications, successfully launched earlier this week from a European spaceport. Its launch weight was 6,910 kg, and it is "distinguished by a giant, 60-foot (18-meter) wide S-band antenna that will be unfurled in the coming weeks. Once the satellite's two solar wings are deployed, TerreStar-1 is expected to have a wingspan of about 106 feet (32.4 meters). ... It is designed to provide mobile voice and data communications in North America to smartphone-size handsets using the 2-gigahertz, or S-band, portion of the radio spectrum. The system is designed to function with a network of ground-based signal amplifiers to permit service in areas the satellite cannot reach, such as urban canyons and areas outside the line-of-sight view of the spacecraft." Video and details of the launch are available from the ESA.

RickRussellTX writes "Comcast plans to offer 4 megabits/sec WiMAX services to customers in Portland, Oregon starting tomorrow. Branded as 'Comcast High-Speed 2go' and '4G,' the service will require a $44.99 per month subscription in addition to existing Comcast home service. For $69.99 they will offer a dual-mode card with access to both Comcast WiMAX and Sprint's national 3G wireless network. Future rollouts are planned for Chicago, Philadelphia, and Atlanta. Say what you will about Comcast (and I know many Slashdot readers have plenty to say about Comcast), this is a daring attempt to bypass entrenched cell phone companies with a direct-to-consumer wireless service."
