yupyup.. my first one did it shortly after buying it.. and my replacement's doing it now, i think it has to do with not enough padding where the ribbon is inside, eventually, after LOTS of sliding it opene and close, it starts cutting it. and i've been VERY careful with this one..
i REALLY don't want to have to go through the whole "reinstalling" of everything i have one it, but i'm off to sprint store tomorrow...
