How to Unlock your iPhone 3G or 3GS 4.0, 4.0.1, or 3.1.3
Apple and AT&T can keep changing the baseband and the firmware on the iPhone as much as they want and hackers are gonna stay ahead of them, especially now that jailbreaking is legal. This new video will show you how to unlock a jailbroken iPhone 3G or 3GS with iOS version 3.1.3 or 4.0.1 and basebands 5.12.01, 5.13.04, 5.11.07, and 4.28.08.
