ultrasn0w unlock for 3.0
As promised on Tuesday, the unofficial iPhone Dev Team has revealed ultrasn0w, carrier unlocking code for the iPhone 3.0 firmware. Creators note that the software injected into a phone's baseband is the same as that in yellowsn0w, designed for iPhone 2.x; the difference is simply the use of a new hole in Apple's security, found by someone outside of the Dev Team. The release of ultrasn0w is being delayed until Friday, to prevent last-minute interference by Apple.
The Dev Team notes that installing ultrasn0w first requires jailbreaking, which opens up access to unofficial apps. The program should already be compatible with the iPhone 3GS however, as it uses the same targeted baseband. The ability to crack the phone is said to be dependent on whether or not current jailbreaking tools will work.
