firmware 3.1.3

Blacksn0w RC2 is now available for those looking to unlock their iPhones running firmware 3.1.3. Beware however, this will not work with the latest baseband version 05.12.07. If you've updated your iPhone to 3.1.3 using Apple's official firmware you are out of luck.

Those updating their jailbroken device to iPhone OS 3.1.3 using PwnageTool 3.1.5 have taken advantage of Apple's battery fixes without altering the baseband from its current unlockable version, 05.11.07. In this case you can now download blacksn0w RC2 from Cydia.

How can I jailbreak and unlock my iPhone? This used to be a simple question with very few answers. Now that there are so many different models floating around determining the answer is more complicated. Add in multiple combinations of baseband, firmware and boot loader on this hardware and figuring out which solution will work can become very confusing.

A new resource on the web seeks to change everything by organizing all known jailbreak and unlock solutions in one place, along with tutorials and other information. The iPhone & iTouch Jailbreak / Unlock Matrix has all of the answers you seek including a place for users to post comments.
