Recently (the past 2-3 weeks) I've been having an issue getting my iphone to charge. I'm using the charger that came with the iphone, but whenever I plug it in it gives me the "this accessory isn't supported" error and it won't charge. I've tried using my laptop to charge as well as a wall outlet and have the same issue. I then have to turn the phone on and off and hope that it will work. If I take this into the genius bar and complain do you think I can get it replaced on the spot?
