hey guys. i had to restore my iphone (its the one with the silver back so not 3g) and now i need to unlock it again. what is the best software to use? the lady at mobile solutions suggested ziphone. i would prefer to just unlock it and not jailbreak it, but i dont even know if that is an option. ive never unlocked a phone before so something that is some what easy to use, i just dont want to screw anything up. thank you.
