when you first buy it if you paid best buy to put it on all you have to do is bring the iphone to the store and they will put a new one in. DO NOT REMOVE PROTECTOR LET THEM DO IT.
IF YOU DID NOT PAID BEST BUY TO PUT IT ON MAKE SURE YOU HAD THE PRODUCT REGISTER TROUGHT ZAGG AND THEY WILL SEND YOU A NEW ON, YOU HAVE TO SEND THE OLD ONE BACK. REMOVE AND PLACE IN A PIECE OF PAPER AND MAIL IT OUT. check out zagg's website for details.
