Blacksn0w RC2 Unlock for iPhone 3.1.3 05.11.07 Baseband Released in Cydia

Steve – the guy who was behind PushFix 2.0 (the first real fix for Push Notifications) for unlocked iPhones has just released Blacksn0w RC2. This version of blacksn0w is basically a repackaged version of the original unlock released by geohot, and the fix which was recently released by MSFT Guy for 05.11.07 baseband on iPhone OS 3.1.3.

1) Checks your *real* firmware version using your kernel version (this avoids using the reported firmware version which might be "faked"). Only installs if you are really running 3.1.2 or 3.1.3
2) Checks your baseband version – only installs if 05.11.07
3) Properly backs up and restores your configuration if uninstalled


If it was too hard for you to patch blacksn0w manually, you can use blacksn0w RC2 to do the job for you! Simply follow the simple step by step guide below to unlock your iPhone 3G and iPhone 3GS on iPhone OS 3.1.3 05.11.07 baseband using blacksn0w RC2. iPhone 2G users should follow the guide posted here (Mac version of the guide here).
