Is O2 UK Hinting That The Next-gen iPhone Will Support Video Calls?

The lack of video calls has been an irritating issue to many iPhone users who view video calling as an important feature of modern phones. Many rumors have been hinting that the next generation iPhone, the iPhone 4G, will be getting a front-facing camera, and will support video calls. Now it seems that the O2 UK site has listed the price of video calling for iPhones in its tariff chart. Could this be an error by a sloppy designer, or is it an accidental leak, and a sign of things to come? Is video calling an important feature for you, or do you think that it’s just a waste of time?
