So I suppose the complaints littering the Apple forums are just coincidence. I counted 20 in one thread alone. The writer at iMore realized his iPhone 5 was bent and he had no idea how it happened. Then he went on to say anybody who didn't realize metal bent was stupid. Himself included, evidently.
Sorry, from what I have seen, combined with basic knowledge of aluminum and some common sense, I don't need any more proof. Aluminum is not a good material to build phones out of. Period.
Where is the proof that the phones were bent in their pockets, like they are claiming? They haven't proven anything.
