Why I can not verify iphone 4 serial number on Apple website?
I got this message: "We're sorry, but this is a serial number for a product that has been replaced. Please check your information and re-enter your serial number. If your information is correct, you may need to contact us." . Please why? how to solve this case please? It is still alive on AT&T carrier. Many thanks
iPhone 4, iOS 5.1
