Tmo SK would'nt stand for abuse. I've dropped SK2 several times and it's internal radio hardware gotten damaged that I couldn't send or receive on air. IT's my 2nd or 3rd sk2. It's keyboard was a champ cuz it last long than SK1 !! .
Now I have BB Curve and I accidently pulled out my belt holster out of pocket(my new belt holster just had a broken clip cuz of cheap quailty swivel riviet) and my BB Curve slipped out of it's holster and flew 6 ft foward in air to driveway pavement and suffered a scrape on it's head and right "knee". It's back cover flew out too but not broken. I snapped back the cover and groaned


at brand new "damaged" BB Curve which was only a month old!!! It still runs like champ anyway. Luckily, the screen window are still intact that what counts. If screen got scratched ect. I would trade in for new one. I don't like scratched screen!! Sorry for my pickiness. I just want to have a clear unobstructed view of screen!!
There is a Youtube video about "blackberry Tossup" maybe look for Tmo SK tossup. There's the one with guy with hammer (not me!!) smashing the SK2

. Maybe that would help you to decide which one is toughie.
