I've got an Otterbox Armor case for my Iphone 5 and I need to get it replaced under warranty. Otterbox have a process in place whereby you email them a photo of it and the product code plus serial number. They should be located on the inside of the case. I've looked everywhere, but cannot locate either the product code or serial number. Any ideas folks?? Oh and it was bought from a reputable shop, so don't think it's fake.
