iPhone 3.1.3 Jailbreak with PwnageTool 3.1.5

iPhone Dev Team has released PwnageTool 3.1.5 for iPhone OS 3.1.3 jailbreak. It will allow iPhone/iPhone 3G/3GS users to jailbreak the iPhone OS 3.1.3.

From the iPhone Dev Team blog,

iPhone 3G and 3GS unlockers should always be very wary to update their firmware. This is no exception. If you make a mistake along the way you may find yourself updating to official 3.1.3 in which case you will lose your unlock, possibly forever.

iPhone 3GS users (regardless of unlock) should stay away from this and all 3.1.3 jailbreak tools unless you know you have your “SHSH hashes” backed up via Cydia. That’s because if you make a mistake you may find yourself stuck at official 3.1.3 with no way to jailbreak or come back down to 3.1.2 to jailbreak.

More information about iPhone 3.1.3 Jailbreak with PwnageTool 3.1.5 is available on the iPhone Dev Team’s webpage.
