iPhone Dev Team releases 2.2 jailbreak

Just two days after Apple released its iPhone 2.2 update, the iPhone Dev Team has released a jailbreak of the firmware.

The team on Saturday posted to its blog QuickPwn for 2.2 and Pwnage for 2.2 for Windows and Macintosh machines along with instructions on how to jailbreak iPhone 3G phones on 2.2.

The blog also includes a word of caution about baseband, the chip that controls the connection between the phone and the mobile phone network:

Think of it like a cable modem or other peripheral that is attached to your home PC that needs occasional updates. When a software update is released and presented to you within iTunes the baseband is sometimes updated (to fix bugs or add new features). The 2.2 update for the iPhone 3G contains such an update, so running the vanilla updater straight away with iTunes will reprogram and update the baseband. This could be bad for certain people, depending on your ultimate aim.

The iPhone Dev Team is still working to unlock the 3G, but it has proven a tough nut to crack, mostly because of the baseband technology. You can unlock your iPhone 3G to use it on another carrier by modifying the SIM card, but what the iPhone Dev Team is trying to accomplish is a software-based unlock that you would just download and install.
