Clinking noise?

[CovKid66]

This was reported early on when these things first came out too. It has to do with the back cover. Chances are you've got a small 'bulge' on the rear cover, half way down, on the side opposite the volume keys? Is that where you can get it to click too? Failing that, it's around the same area on the volume key side??? Seems to be related to the small plastic clips integrated into the cover that latch to the phone.
