You still have to upgrade it again an d pay a little extra ......its only like 2 or 3 more dollars a month

We do ! go to XM/SIRIUS radio on your computer and under mobile there is a two free weeks try out ...... but it gets a little expensive after that........ Did you try pandora ? Its FREE ? lol

Don't really know about channel availability on the iPhone, but I had XM for my BB for way too long before finally cancelling it. Pandora, Slacker, Nobex, etc., for me, seem to give me more options and variety, and the free versions are pretty impressive. Just never liked the limited choices of channels on XM thru ATT. Is it different thru other carriers?

I probably have listened to Pandora more in the last 2 months on my Bold than I ever listened to XM on my Curve, even though i paid for it for over a year!!

Still looking for a radio app, i.e. for real stations for talk, sports, news, etc.  What are some of the best options out there?
