Hey Jaxov, I’m an iPhone 4 user. The thing is, I have successfully unlocked my iPhone 4 from AT&T and used it over T-Mobile. All is working well. But my wife ran a software upgrade last week and restores my iPhone 4 and her iPhone to iOS 4.3.3 (04.10.01 modem firmware) through iTunes. But the new iOS removes the unlock, I can’t use my T-Mobile SIM, where all my contacts were listed. So repeat the instructions on how to use Gevey SIM but still doesn’t work. Should I get a new Gevey SIM and try again? Will I be able to unlock on iOS 4.3.3? Please help. Thanks.
