I have an XV6700 Pocket PC/Phone (Verizon Wireless) running WM5 that I use to listen to my scanner stream from home. I can either use my WinAmp/Oddcast stream or my Streamwebtown feed using Resco Radio on the XV6700. The url for either feed is entered into Resco Radio's menu and from there I just click & listen........using Bluetooth of course ;-)
Picture of my mobile set-up using this method is attached. The scanner stream is the lower right menu tab on the Resco Radio interface (hard to see, but it says my scanner).
