i just got the blackberry bold 9780 from tmobile in black and i don't like how it looks with a full on case, it makes it look bulky. the lady at the retail store told me that i could get a case for the back only, and she showed me hers and it was nice, and not bulky at all. does any one know where i can get one of those? a good looking rhinestone one that's not over 30 dollars? thankyouuuuuuuuuuuuuu
