http://www.minixm.com lets me listen to XMRadio through the Q. Not sure if that will work if you don’t have a subscription already. According to QUsers there’s a similar capability for Sirius radio, but that involved a zip file full of stuff and I’m already overwhelmed by the number of ways I can run down my battery entertaining myself with the phone. 🙂
Finally figured out the volume control for the Slingbox Mobile app. It uses the headset volume control, even through the built-in speakers. Kinda makes sense once you know it… but not intuitive. Guess written documentation would help there.
Still in the problem space… still trying to find a good solution to getting my Outlook notes sync’d. Windows Mobile 5.0 for Smartphones doesn’t include a note app (well, they do, but it’s for recording voice notes, like a pocket dictation machine.)
