Nokia 3310.

Excerpts from a website:

3310 yesterday have passed the craziest quality check i ever put onto it.dropped
from the 3rd floor of convention centre to the 2nd floor during the pc
fair...guess wat,no LCD crack,keypad still functioning,calls can come
though...AMAZING

So people, get a Nokia 3310 for your new year present, its cheap and tough, and u wont keep worrying about it being lost or stolen, cos no one will take it! :P
