I hear a little tiny rattling sound in my iphone whenever i tap it against something (carpet, wall, hand). I first noticed this when i was going to charge my iphone i dropped it on the carpet like 2 inches above the ground and i hear the sound. I've read several other forum posts on this website claiming that the problem is caused by the camera lens. Im also thinking this is true because whenever i tap near the apple logo i hear the same rattling noise. So im just wondering is this just a minor flaw or should i take it back to the att store and make sure. Do any of you guys hear this noise? I just got my iphone like five days ago too so i doubt anything would be broken.
