If you want something to clip to your belt VZW sells a nice holster with felt to protect the sreen and a hinged clip so it will not crack or break from use. If you want something to just slide into your pocket, they sell a "hard/soft" case which snaps around the front and back of your BB but is soft to the touch.
I currently have my curve skinned while using the clip from verizon. I got my skin from EBAY. It is a thin decal like material that doesn't use glue. It is similar to a window sticker. It doesn't mess with the clip at all and will not fade. They were 3 for 10 bucks with free shipping. BERRY ON
