Keeping it clean

[Cerbera]

Just got my Vogue replaced by Sprint.

Apparently a solder was lose near the mini USB port that prevented my phone from connecting to any computer.

Well just touching my replacement phone felt wonderful!

Sounds weird but I tried touching my old phone and it didn't have that "feel." It felt quite gross now that I'm thinking about it.

The new phone feel is not smooth, yet not rough...I don't know how to explain it.

Anyways, anyone has any tips on keep my phone as new as possible?

What is the material on the outside of the black casing made out of?
