Good News for those who are stuck on iPhone 3GS OS 3.1.3 / Baseband 05.11.07 and can’t downgrade to earlier versions because they didn’t saved their Cydia SHSH. MSFTGuy and PushFix fixed the Blacksn0w and firmware 3.1.3 issue and now this unofficial patched version of blacksn0w is available on PushFix Cydia repo. This modified version of blacksn0w adds support for phones running 3.1.3 with 05.11.07 baseband (phones upgraded with PwnageTool or Sn0wbreeze). It also fixes a small bug that appears to make WiFi much more stable
Note : Needless to mention but if you updated your 3.1.2 or less OS to 3.1.3 stock firmware you are out of luck because your Baseband is updated to 5.12.01 and latest BB is incompatible with Ultrasn0w/ Blacksn0w. MSFTGuys patched release is for BB 05.11.07 only.
Download Installation Instructions
Blacksn0w RC2 will be available on MMI repo very soon, if you are impatient one then you can add the source ” http://cydia.pushfix.info/ ” to Cydia and install it now. The package is called " blacksn0w RC2 "
Warning : Blacksn0w for 3.1.3 is still in RC stage and there may be some issues or bugs, for example, if you are faking your OS version to be 3.1.3 and you install the 3.1.3 version of blacksn0w RC2 with 3.1.2 CommCenter, you will cause problems! Your cell and WiFi could be unresponsive until you either uninstalled the package again via Cydia or restored the phone. So if you haven’t left any other option only then go for this release.
