OH MAN GET THE ERICSSON!!! My friend has one, and it's probably one of the sexiest phones I've seen (after the Motorola RAZR, of course). Plus, it's made by Sony, so how could you go wrong?
I personally like Motorola, but the v180 sucks. It's cheap and feels fragile...it like makes weird creaking sounds when you squeeze it too hard. It's basically a budget phone. Avoid.
