Sirius XM, in a valiant effort to stay afloat, is launching an app for iPhone and iPod touch users to access the satellite radio service. Expected out in Q2, no extra equipment is needed to access the content for new subscribers. Although no specific price was mentioned, the company said it would be available to their 19 million regular subscribers as well as the 7 million U.S. iPhone users. This is good news for the beleaguered company since it has lost sales from automobiles and those who just cannot afford the luxury of the music service.
