Finally got some time to reload Orb on my laptop and was able to add some custom conent (sirius urls). Works fine from the Wii in the family room, but the 8310 on AT&T isn't liking it yet.
I was able to stream some other generic internet radio station on the BB, but alas....no luck so far.
I'll keep trying like VJ and see if the 1:15 ratio plays out.
