I gave my old iPhone 3G to my dad and he got it unlocked. The person who unlocked the iPhone also jailbroke it, so it had Cydia and all that stuff. But now the iPhone is really laggy and operates slower. How can I un-jailbreak it? I have to restore it right? But if I do restore it, does that lock the iPhone again? Or will it still be unlocked?
Question about unlocked iPhone's?
