QuickPWN has already managed to release a jailbreak for the iPhone 2.2.1 firmware. The program does not yet provide a solution for owners of unlocked 3G phones, however, as the latest Apple firmware will revert any of the handsets back to a locked state. Nonetheless, the QuickPWN program will jailbreak the iPhone, iPhone 3G and first-generation iPod touch, but currently requires Windows for installation. The developers are likely working on a Mac version, although a confirmation or date have note yet been provided.

The Dev-Team had warned about updating an unlocked iPhone 3G with the latest firmware, and the suspicion turned out to be valid. Firmware version 2.2.1 permanently modifies the baseband, possibly eliminating any future chance of unlocking an updated device. The team is investigating the situation and trying to find an exploit.
