Amazing how many ppl jump to conclusions here. A more likely scenario, IMO, is that he unknowingly hip checked a chair, table or desk with the phone in his pocket. I've dented/distorted a couple of iPhones this way myself. After finally deciding to go with the apple leather case on my 5S, it seems to be enough to protect it from reasonable bumps. I bought the leather case for my 6+ as well, but I can see that I'll need to be a little more cautious about not bumping into things.
