The unofficial iPhone Dev Team has released a new version of PwnageTool, one of its hacking utilities for iOS devices. The updated software promises to unlock some models of the iPhone 3G and 3GS for unsupported carriers when using iOS 4.2.1. It works because the original iPad firmware, iOS 3.2.2, has been discovered to contain the v06.15.00 baseband, which is still vulnerable to an old exploit.
