The Tmob version does have it on the outside, but my gf who owns the Tmob TP2 also complains about the back cover easily falling off. I guess life is about give-and-take.
As an aside, when I first read this thread title I was going to offer that I bet it wouldn't be something a golfer like Tiger Woods couldn't fix. But of course, I restrained myself. Oh, wait. Did I type that aloud? Crap!
