Sheriff Hashim, an American hacker has finally found a new exploit for the new baseband 05.12.01, which regulates the activities of the party machine for all iPhone.
s you know, the iPhone 3G and 3GS Italians, however, are factory unlocked so that the baseband is not as influential for us. Have found the exploit needed to unlock this new version, however, will make it possible to implement a new program by the DevTeam, able to upgrade, unlock and run the Firmware 3.1.3 Jailbreak with lots of updated baseband.
Apparently then, we can quickly get the total and definitive Jailbreak for Firmware 3.1.3, you also the best in the battery and WiFi signal.
Thanks Pavel Nitrox
