yes, you can.
If you run Orb.com on your home PC you can stream TV, movies, radio, music, etc to the phone. If you download the AOL radio app, you may be able to pickup the edge on it too (not sure if it’s offered or not).
just to note though, if you’re trying to stream TV or video in general, you’ll need to be on a Wifi connection. There is no way Edge can handle it and have my doubts about 3g as well
