Tuned.mobi
I think I found this while browsing on Howard Forums. This is a very cool website. It has a complete listing of all radio stations that you can stream on your phone. The quality is surprisingly good too. Some of the sites support mp3 feeds, some wma, and some both. I tested it from both my Blackjack and Treo 680 and it worked great.
I tested out a couple of radio station in the Chicago area for a few minutes and there was no lag and no breakups. The Blackjack has 3G which is pretty fast (see my speedtest). The Treo 680 uses edge, and still the connection was great.
Check it out from your phone: Tuned.mobi.
