Hello, I have an Iphone 3gs with iOS 4.1 and baseband 5.16.07. I paid for the phone to be unlocked, where I got it unlocked said to reset my phone and then do a restore. Well when I try to reset my phone it gets stuck on the apple logo. So I messed around with it to get back to where it was. When I try and do a restore or upgrade to iOS6 in Itunes it gets stuck on the activation part and says that it can't be activated at this time. I don't know if I'm supposed to delete cydia(if possible) before I do a reset or restore so it will unlock the phone. I have switched the baseband around to try and use Ultrasn0w but my service(straight talk) still says no service. I know it's not the sim card cause I can put it in another phone and it works fine. Does anyone have any suggestions?
