My screen on my 3GS has a nasty little scratch in it. I'd like to take it to apple and pay them to swap the screen. But the device is jailbroken. I'd like to keep it that way... Do u guys think I need to restore the phone to factory to have them work on it? Will it matter? Or my other idea would be to bring it in w a dead battery and just ask they swap the screen. What do u guys think?
