My brother drove over his Nokia phone with a car, and it cracked the screen. It was still readable enough to place and receive calls, and it was very easy to repair, but it did take damage.

What was the damage to the car? ;p

When it comes to Nokia 3310, it is a huge dealer of damage, not so much of a receiver. :D

I dropped my N900 so hard (by unsuccessfully grabbing for it as it was falling) that it cracked some the sidewalk's fairly brittle concrete. Had no effect on the phone, no case.
