Is there a way to reverse the unlock on my iPhone? I bought one, activated gophone and unlocked. After a couple days of usage, I liked the phone so much I figured it was worth opening an AT&T account. So I restored my iPhone and opened an account not realizing the restore did not reset the phone to default. Now I am totally paranoid my phone will be bricked at some point even though I have att service. I'm surprised the hackers did not provide an undo, at least one I can find. I can still return it and eat another $40 restocking fee to get another but my screen is mint even though it's a 7 series. No grids, bubbles, or negative blacks. What should I do?
