Video Calls

I've seen in tv shows where people are using an iPhone and they are talking to each other and they can also see each other. Like in Knight Rider for example. I'm curious if that really is possible. Maybe someone call respond to this question.

Since Chip has a job now we're both going to get a cell phone plan and new cell phones. He's been taking our only cell phone to work but it's a pre-paid cell phone which means for $25 he gets 2 1/2 hours to talk. He's calling me all the time and he's calling other places and I just have a bad feeling about it. He's going to need a cell phone plan with an unlimited calling feature, GPS and internet. I figured that we could both have them so we can call each other for free.

I'm going to need one too because as soon as I get a new bike wheel I'm going to be riding my bike again and when he calls me I'd like to be on video phone chatting so he can see what the bike path looks like. I think that would be cool.

Anyway, please, if someone can respond to let me know which cell phone has that feature. I'd like to get blackberries but iphones will be cool too. I just need to know which phone is best for video calls. Thanks
