While the rest of us were glued to our television sets witnessing all the Superbowl action, the miracle workers at the Dev-Team went ahead and released the PwnageTool 3.1.5 for Mac OS X which jailbreaks the iPhone OS 3.1.3! The updated utility not only creates a custom iphone restore file but also strips the OS 3.1.3 update file of its newer baseband modem so that it can be replaced with an older version that is compatible with ultrasn0w. Pure genius is what all we can say !
Users with the iPhone 2G, iPhone 3G, iPhone 3GS (baseband 04.26.08 and older bootrom models), and iPod Touch (1G and pre-jailbroken 2G) devices can try this baby out. Once you update the custom .ipsw , you can follow the steps in our previous guide (here) as the process is identical. Also head over to the official Dev-Team blog post which lists all download mirrors for PwnageTool 3.1.5.
