FTP: "The issue I have with getting a replacement is that I purchased this iphone 4s from someone who upgraded to iphone5. Which means the serial number is not matching with my apple account.” From my personal experience, I didn’t have any trouble getting an iPhone replaced even though it was not purchased using my account. Apple checked the serial number to verify the Warranty status, and I was given a replacement at the Appel Store Genius Bar. I am not sure if Apple maintained a blacklist of reportedly stolen iPhones. This past Summer 2013, a friend of mine bought a used iPhone from Craislist (red flag #1) and found out that the phone was reported stolen 2 weeks after. The iPhone was somehow blacklisted from connecting to AT&T network.
