Old thread, but my N9 started creaking recently, and I've had it since early December. It does it when I push the screen on the left side, right near where the screen meets the plastic body, and about 3/4 from the top. Must be the screen coming apart from the body, ever so slightly. The phone felt so solid when I got it that this does bum me out. Especially since I have no hope of warranty in the U.S.
