iPhone 3.1.3 Jailbreak Not Possible with Blackra1n Yet
George Hotz (aka geohot) has confirmed via his twitter account today that his blackra1n and blacksn0w tools are currently not compatible with the latest iPhone 3.1.3 firmware. This new firmware brings 05.12.01 baseband for iPhone 3GS and iPhone 3G which restricts jailbreaking and unlocking on newer devices.
Yesterday Apple pushed a new firmware update for all iPhone and iPod touch users which brought some important security and bug fixes. Features wise, there was nothing new to be seen in the firmware. Since this firmware updates the baseband to 05.12.01 on iPhone 3GS and 3G, therefore you are required NOT to update to this firmware if you want to preserve your unlock on iPhone 3G and iPhone 3GS. Jailbreaking will also NOT work with iPod touch 2G(new MC models) and iPod touch 3G. The only devices which can be currently jailbroken using redsn0w 0.9.x is iPhone 2G and iPod touch 1G/2G(older non-MC models).
Note for iPhone 3GS, 3G, iPod touch 2G(new MC models) and iPod touch 3G We strongly suggest that you stay away from this official upgrade until and unless the DevTeam or George Hotz releases new jailbreaking and unlocking tools for 3.1.3 firmware. We will let you know when it will happen.
