Installed this radio app last night and was quite impressed. It picks up loads of UK stations but is still very buggy. It crashed back to the springboard quite a few times. But when it works its great.

It is supposed to work over 3G, Wifi or Edge but only works over wifi for me. It goes to the radio player screen but always says Loading and the gprs (edge icon) stops spinning after and few seconds. Because I have a first generation iphone on tmobile with no edge in my area does this mean I can only use this app on wifi? (I am in the UK by the way)
