Today my good friend who is a genius at the apple store in Sacramento was working today. Anyways, every single iPhone 4S on display had the camera rattle. Some were very loud, some were quieter than others but every phone had it like mine. My friend said its normal. Next, every iphone 4S had the wiggly home button. Now some were very wiggly like mine, others were just a little. Didn't find one that didn't wiggle. Lastly, every single iPhone 4S had a different tint. None were the same. I saw very blue, white, yellow and even a green tint which is new. Anyways me and my friend were comparing them all. Didn't take more than 10 minutes all together. I would say the most solid phone I saw was a C38 16GB at&t model. Hope this helps some people.
