My 3G, taken with my new 3GS. Fell from a height of about 3 feet onto a linoleum floor.
That phone has been through hell and back though. It has sand underneath the screen from Iraq, it's fallen onto concrete and been kicked 10 feet, and even after the fall that broke the screen, it still worked. I tried an Otterbox on my new 3GS and just couldn't get used to it. I settled on a little leather slip case, so at least it will be protected while it's in my pocket.
