Tech carries serious risks
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.
Installation requires several steps, including downloading the iOS 3.2.2 firmware from Apple. The Dev Team warns that there are several risks, such as the inability to do a full restore, or even downgrade baseband. The process also invalidates warranties in a way that should be relatively easy for Apple to detect. Owners of an iPhone 3GS using the old bootrom are advised against upgrading to iOS 4.2.1 in the first place.
