In the past, I've dropped mine in the toilet and put it through the washing machine. A couple days ago, I left mine on the playground at an elementary school as well. Goodness only knows what fate might have befallen it, but I realized it was MIA about ten minutes later and went back for it.
I've dropped my phone on concrete from about 3.5' about 100 times and no problems. I dropped it the other day on a wood floor from 1.5' and the screen cracked. -__-
on my older cellphone, the screen was all cracked and miracle, one day it all peeled off in a single layer, and the screen wasnt cracked no more... its like the phone had a second screen under the cracked screen.
