It is black and white unit with basic features and a led flashlight on top. The main advantage to this is that the decreased features provides for a long battery life. I dont have to charge for days. The one i use for my sun is the Nokia 6085 clam shell. It is compact but i am wary of breaking the hinge. It was a promo unit from sun which i added money for. The smart number i use is housed in the Nokia 6600. The one that looks like an egg is a pretty sturdy unit. No problems despite several drops.
