My 4s rattled a bit when it was new. I wasn't sure at first if the buttons were responsible for the rattling, or if it was something internal. Then I dropped it a couple of times while spinning it around in my hand to locate the side with the button I wanted to press, and that made it stop rattling for some reason. The front and back glass slabs now slide around a bit, though.
I'm more or less dumbfounded at the popular perception of the iPhone 4 as a "great" industrial design. While it's definitely a great phone, if they don't return to a curved back with the next model or otherwise provide some tactile cues that help the user sense how it's oriented as it's being withdrawn from a pocket, it'll almost be enough to send me over the fence into the Android camp. Failing to move to a bigger screen will certainly do that.
