Satellite Radio for Sprint phones
SIRIUS Satellite Radio has signed a deal with Sprint to offer select SIRIUS content over the Sprint network. It is said to be available soon. Right now details are still sketchy, but we'll find out more when both Sprint and Sirius give us more specifics later this year.
Sprint's current Internet radio service, MSpot, contains 13 channels available for $5.95/month (or for free if you're a Vision Multimedia Services subscriber). I expect that this new deal will be a combination of MSpot and SIRIUS, but what the new service is branded under is probably still under debate.
