BlackBerry Curve 8320 -wifi

.

Setting the data rate to 12 kbps and mono was the trick for me. I'm off streaming with moodio on Wi-Fi and GPRS/EDGE. I listen mostly to talk radio, so the 12 kbps is just fine.

I did notice that my Blackberry Curve 8320 cannot hand-off between Wi-Fi data streaming and GPRS data streaming. It might be difficult to switch some of the parameters on the fly such as bandwidth and protocols. I do know that GPRS/EDGE uses WAP instead of HTTP to surf web pages. BTW, UMA is voice over Wi-Fi with GSM signaling.

On GPRS/EDGE, it eats up your data megabytes. While on Wi-Fi, it's free. The at home router brings huge value in this respect. I don't have to worry about my minutes while on it.

I have a T-Mobile/Linksys "HiPort" WRT54G-TM router at home. It works well for streaming to my Blackberry Curve 8320.

I gave my girlfriend a different T-Mobile/Linksys router. It's also working great for streaming m.moodio.fm to my Blackberry Curve and her son's T-Mobile (HTC) Shadow.

v4.5.0.81 (platform 2.7.0.78)

OS 5.0 is recent enough.
Did you also try changing the Yourmuze audio setting to mono or stereo (not parametric stereo).
