In my case, it's a Nokia 3310. The reason why I chose to paint this particular phone is because of the changeable covers. (And it is my phone. And it has Snake II on it.) If you screw up, you can buy a new cover and your phone is as good as new. That's not so easy as with a normal phone, is it?
If you got your paint, make sure it's made for plastic, and the right kind of plastic! Probably, if you're painting a phone it's a hard plastic like PC (Poly-Carbonate). Most acrylic paints are good for that type of plastic. I used spray paint for models from Tamiya.
I also recommend to use a plastic primer!
Update: I have made another cover, now with some extra awesomeness: a Thinkpad badge I bought on eBay =)
