I had the original storm and upgraded to the storm 2 recently. I have always gotten my cases from
BlackBerry Storm2 Cases. They offer some name brand cases like otterbox, but I order their brand of leather slip cases. I keep my phone in my pocket, and like how it protects the phone but I can easily pull it out as well. That's just what I use though, just look around at blackberry accessories sites and find one that suits your needs.
