Iphone 3gs was locked to vodafone, friends promised to unlock and said no jailbreak. Got phone back and saw it had cydia and was on Ios 4.21. also it had been somehow set up to use a TMN sim (another carrier here in Portugal) which is what I wanted it unlocked for. I understand the jailbreak/cydia enabled the other carrier sim to work. I turned phone off and whilst holding home button plugged into itunes. selected restore and it seems to do it and verify but then all I get is spinning icon next to iphone listed on left side and phone is not asking me to insert a sim. If i do insert a sim I am not asked to unlock the sim and the phone just wants to be connected to itunes, yet itunes is not finishing the restore process. Ideas?
