What i mean is that if you hold the n800 with the screen facing you and you tilt it to the left, it sounds like a ball rolling to the left...and when you tilt it to the right, it sounds like the ball is rolling down to the right corner....I cant duplicate the noise right now, so you could be right. Maybe i was just drunk and paranoid Yes there is a definite sound when you shake it, thats always been there.
