I have an iPhone 4 that is locked to AT&T. I am currently on and off the phone with them every few minutes to get an unlock code. If this fails, if I purchase the Gevey SIM for iPhone 4 will it work? It says this on their site:
The original GEVEY Ultra unlocks your GSM iPhone 4 and will work for iOS version 4.1, 4.2, 4.2.1, 4.3, 4.3.1, 4.3.2, 4.3.3, 4.3.4, 4.3.5, 5.0*,5.0.1*,5.1* and 5.1.1
Does this mean it is incompatible with iOS7?
