I have an iPhone 4 on iOS 5.0.1 and preserved baseband 04.10.01, does anyone know if the Gevey Sim will work for this since the baseband is preserved, or is there any other way to unlock the phone? I do not care if the phone is jailbroken or not, it is on AT&T and I just need to use it internationally, of course AT&T won't give me an unlock code.
