Samsung SGH-ZX10

Maybe, but we're talking about the United States, not Europe. Cingular has to establish a network to call on first. Video calling isn't going to be useful without a large, functional network. In a perfect world, US carriers would offer advanced phones for reasonable prices. The reality is that they don't. The majority of cell phone users are content with phones that simply makes calls. They can't push advanced phone services if no one wants them. A know a number of people who have Verizon Vcast phones. Not one of them has signed up for Vcast because they aren't willing to spend money on video displayed on a sub 2 inch screen. If consumers hesitate to purchase current 3G services, it would be suicide to introduce more services that are even more expensive (adding up the cost of new handsets you and your friends need to talk plus the small amount of monthly video calling minutes).
