Samsung N400 - one of Sprint's 3G Vision phones. I've had Sprint for a few months and it's been OK. I haven't had any trouble with them, but I've heard about a lot of people who have. Battery life is a down side though - I even got the extended battery and it only lasts a day if you do a lot of web surfing or games (stuff that uses the backlit screen). Still, I'm happy with it, and it's really nice to be able to get on the internet while I'm waiting to get into a restaurant or something.
