Developer of PushFix 2.0 app for Push Notification on iPhone has just released Blacksn0w RC2. This version of Blacksnow is a combination of the original one(released by GeoHot) and the FIX which was recently released for 05.11.07 baseband on iPhone OS 3.1.3, so if you are having problems in manually using Blacksn0w to unlock your iPhone then you can use Blacksn0w RC2 to make the job simple for you.

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

3) Properly backs up and restores your configuration if uninstalled
