We don't have a FreePartyRadio.CoM iPhone application (yet?), but there's a few different ways to listen to us on your iPhone.
This is a free application anyone can download for free from the Appstore.
Just put in " http://freepartyradio.com/radio.pls " as the Station URL, and FreePartyRadio as the Station Name, and click save.
You can now tune into FreePartyRadio.CoM wherever you are, as long as you get fast enough 3G to stream without buffering. Make sure you don't have a limit, as radio streaming takes up quite some bandwith!
