So I got my iPhone 5 today (yaaaay) and the first thing I noticed when I picked it up was that it rattled. Not only could I hear the rattle, I felt it. I have the camera rattle on the iPhone 4 so I know what that should sound like; it's completely different. It feels like there's something heavy and solid inside the phone that's loose. When I shake it, it feels like I'm shaking a spray paint can (and sure sounds like it too). Funny thing is, the phone itself is perfectly fine (except for the scuffgate; 3 chips, 2 scratches and dirty seams between aluminum and glass). It makes calls, does data lightning fast, etc. but this rattling issue is bugging the heck out of me. Is there anyone else here that has a similar issue? Do you think if I take it to the Apple Store they'll have any units to replace this defective one with?
