[Step 2 ]: PwnageTool will give you an option to select your device . Choose your device and click next.

[Step 3 ] : Now you need to download the correct iOS firmware, which in this case is iOS 5.0.1. PwnageTool will automatically scan for this firmware on your desktop. If it can’t then just use expert mode to browse for the location of the firmware on your Mac and point PwnageTool to it

[Step 4 ] : Now it would ask you to build the custom IPSW. Just tell it where to save your custom iPSW file.

[Step 5 ] : After the build is complete follow on screen instructions to place your device in pwnedDFU mode to restore from iTunes using your newly created custom IPSW.

[Step 6 ]: Now this is the most important part. Make sure that you select your custom IPSW when restoring from iTunes otherwise you would end up upgrading your baseband, which is exactly what we don’t want to do.
