All users who were successful with this free of charge unlock solution, had to restore their device to get their iPhones unlocked because this free unlock process requires iTunes interference and also At&t releases your unlock application only when you connect a Deactivated iPhone to iTunes.

If your iPhone 4 or iPhone 3GS is Jailbroken, which you plan to get unlocked for free, then you should be careful you need to follow recommendations from MuscleNerd.
