Att is sending a warranty replacement due to the phones USB port or motherboard messing up, anway I dropped my phone after the fact and cracked the screen but it still functions flawlessly so I was thinking since ATT wont take my orginal phone back I could just tear both of them down and swap the screens out. But I am unsure if there is a way ATT could tell if I had take the phone apart. I think I would have to pull the sticker in the battery compartment so the IEMI number match. I have already tried to pull the sticker off mine and it will come off without any damage. Do you think it is worth a shot???
