iPhone OS 2.2 Jailbreak Debuts

Our sister site, News.com, reports that, 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, which has been at the forefront of every jailbreak and unlock procedure for each new iPhone model and OS iteration, is apparently very close to the elusive unlock for the iPhone 3G. A recent post to the team's blog states that the following tasks have now been accomplished: Unsigned code execution on 3G baseband, Reverting 01.45 baseband to previous versions, and ore.
