Does your iphone 4 rattle?

I KNOW WHAT IS IT!!! IT'S THE CAMERA.CHANGE THE CAMERA AND THE RATTLE WILL STOP

you can try stopping the rattle (if it's the battery) by pushing the front down:

I just shook two htc's one 3GS, and my 4s. All of them rattled. This is obviously not a fault.

you were right! thanks.

Mine rattles and I've had it since the 23rd of last month. The sleep button moves slightly aswell. Annoying but I can live with it :) as above its near the camera and you can tell when I place it on the table. Only noticed it today

Just realised this rattle today from my iPhone 4. Definitely my power/sleep button as the rattle disappear when I shake the phone while keeping my finger over the button.

Yea i get what you mean bud, but when i first got my iPhone 5, about 1 month after it started doing it... Thoughts?

doesnt work..
