So I woke up in horror this morning to find that my girlfriend had tripped over my iphone cord and sent it flinging towards the floor 😱... It appears to be unharmed. It was housed in a case and the case seemed to have taken most of the impact, but now there is a rattling noise on the inside... Like a little lose piece or something... any ideas on how to get it to stop rattling? (I would like not to have to take it apart and void the warranty)
