Friend does that kinda crap all the time. He's thrown it at his door, wall, concrete ground, etc. Everytime he does it hard, the back flies off, and the battery flies out. Somehow, that phone is still running...Its an LG VX5400.
Lol, my friend does too. He's broken like three Razers doing that.
And yet mommy keeps buying him new ones.
*sigh*
