I've dropped my iPod Touch 4, iPhone 4, iPhone 5 as well as my iPhone 5S all together totalling around 50 times, at least. Never had any of them with broken screens. the most I've gotten was a knick on the edge where my phone hit the floor.
But, again, I don't see what that has to do anything with this thread...
I've had that for a bit, but it's just too big and gets annoying after a while.
(Plus it doesn't work well with the fingerprint scanner on my 5S).
