Don't buy a V710, stick with cingular if you want a cool phone with bluetooth. I'm a major hater of the V710 on HOFO, and I really really tried to contribute to making it better. It's just not a phone that will make a hard core computer user happy.
Everything VZW CS says is a lie. If you have a camera phone, you are already signed up for NAMOU, national access minutes only useage. I think they changed the name recently, but its the same. Your phone will connect when your computer makes the call to #777 and it will be a relatively high speed connection. The reason you can't DIAL #777 is because that's a data link, it just opens the phone up to the 1x network, not really dialing a number, just logs in.
IF YOU EVER DOUBT SOMETHING THAT CS SAYS, CALL BACK. Cant say that enough. If you get someone on a bad day, they will make your life hell. If you get someone who just got to work, and isn't all stressed out by teaching people how to text message and explaining that when you drop your phone in a toilet it won't work anymore, they will usually give you the good answers. If something isn't quite right, call back.
