I've had good luck with Tune In in the past.
Also, you should be able to stream the Stretch feed from Ohio Athletics by hitting
http://client.stretchinternet.com/client/ohio.portal (again, this works on iOS, I haven't used Windows Phone, but it is a standard audio stream).
Trying Power 105 by going to
http://www.athensi.com and clicking the WXTQ link in the right-hand rail, just as you would on a desktop yields a link to their own app on iOS, but it is obviously detecting your browser, so it might be worth trying to see what it does on your device.
