I'm not aware of many 3G phones on the market that do not support 3G video calls. My cheap SonyEricsson from 2006 does. My Nokia 6110 Navigator does. The cheap C5 does. The X6 does. - Browsing through the spec sheets of a few 3G models, I only found 2 that did not support standard 3G video calls, the N900 being one of them.
