I have the MobiTV software on my telephone (cingular 8525) and it’s really pretty cool.  I have used it several times to watch sports, get weather channel forecasts and even news.  It only takes a minute or two to load completely even in remote areas and it’s streaming is pretty high-end, once it starts coming into your phone it doesn’t hardly get interupted.  The sound and video quality are also pretty good considering it’s rendering on a cell phone.  Very slick stuff.
