Blacksn0w RC2, the unlock tool for iPhone 3.1.3 05.11.07 baseband has been released and now available for download from Cydia.

This is not the official tool, but an unofficial one released by Steve, the guy behind the PushFix 2.0 tool. Gehot is not the one to release this tool. Blacksn0w RC2 is a repackaged version of the original blacksn0w RC and the fix which was released two days back.

Blacksn0w RC2, Unlock iPhone 3G/3GS 3.1.3 05.11.07 Baseband

This is how Blacksn0w RC2 works as given on the official forums:

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

Remember to first add the source “http://cydia.pushfix.info/” and then install Blacksn0w RC2 to unlock your iPhone 3.1.3
