Gist: iPhone 3GS jailbroken despite Apple Inc.’s efforts to thwart jailbreak. Jailbreak, known as Purplera1n, done by 19-year-old George Hotz, an early iPhone modifier.
Despite Apple Inc. (AAPL)’s constant anti-jailbreaking efforts resulting in delays with every new device or upgrade, the community again has succeeded in jailbreaking the new iPhone 3GS, resulting in full access to the filesystem and ability to run unsigned software.
The new exploit, installable in Windows platforms to iPhone 3GS devices, is available immediately and is known as Purplera1n. The creator of the exploit is 19-year-old George Hotz, who was also the first to hardware-unlock the iPhone.
Interestingly, this comes before the full unlock by the main iPhone community software organization known as the iPhone Dev Team. They have a temporary solution, but only for those who do not wish to unlock their iPhone 3GS in the future.
Apple is continually patching the known methods of jailbreaking, unlocking, and other exploits that utilize the device for unauthorized purposes, and while they succeed in stagnating the time-to-delivery for jailbreaks and unlocks, the device eventually becomes exploited.
