Get this:
JET BLACK/FROST WHITE PREMIUM SKIN CASE FOR 8800/8820/8830 - *CSKBB8800-BK

If you use a holster or case you may want this:
SUPER SLIM RUBBERIZED HARD CASE & HOLSTER COMBO -Blackberry 8800/8820/8830 - BD2-CSRSC2BB8800

The rubber skin is excellent. Stops it from slipping from your hand and sliding around the car. I keep my BB8800 in my front shirt pocket and it hasn't fallen out once since I have the skin.
