I agree with the BBmessenger, it works great. For a case though, i really like my skin that is on my phone. it makes the phone virtually scratch proof, and looks like nothing is on it. Its available for any type of devise, and has a lifetime warranty (and no i do not rep the company, i just love the product.)

The sponsored company Seido is also a good product. I had a rubberized thin cover for my old blackberry and it was great. I like the invisible shield better now though because its, well, invisible. lol
Best of luck in your search.
