Downgrade's your baseband to that of the 1.1.2 firmware
This handy package will downgrade your baseband to that of 1.1.2. When it is done, you can do a full DFU downgrade to 1.1.2, and you will have a perfectly functional 1.1.2 iPhone. You can also upgrade your 3.9FAKEBLANK bootloader to 4.6FAKEBLANK after installing this package. Once this package has finished installing, it is safe to "uninstall" it through installer. Don't worry, it won't uninstall the package, just remove it from the list of installed apps in installer.
