I know this sounds stupid but I have seen some people that treat their blackberries so horrible, I have a Blackberry 9930 and I have a screen protector, case and holster for it. I may take care of mine a little too much but I have seen someone that's dropped theirs on the floor and the screen cracked, some have scratches or have threw them on the floor or at the wall. How well do you treast your blackberry?
