Suddenly you drop it and it breaks!
It's not my phone. But, iPhones are tough sons-a-bitches though, I've seen plenty dropped and haven't seen them break. My sister somehow managed to break roughly ~5 iPhones in her lifetime so far, though.
Wait, what are you trying to get at by posting that? Are you calling me out for using a Jailbroken iPhone/thinking I jailbroke my iPhone?
