Been through four 4Ss and now three/four iPhone 5s, as well as three iMacs and numerous other bits. It's more a warines of replacing a device when it is technically fine and could be replaced with something worse. The phone is technically damaged, that's the main thing.
Made a post a week or so back on my Apple experiences, you'll see why I'm so concerned.
Just hoping to get some opinions before deciding whether to swap it out. Not going to bother if the rough finishing appears to be common for all devices.
what are you doing to your phones / macs??
