Satellite radio provider XM is preparing to launch a native iPhone client to access its commercial-free broadcasts. Ars Technica notes that the company's executive vice president and chief marketing officer Vernon Irvin spoke to attendees at the Federated Media Conversation Marketing Summit that his company currently streams to select AT&T phones, and will expand to natively support the iPhone at an unspecified future time.

While details on the move are lean, the application would most likely be available from the App Store, and that billing would most likely be handled through AT&T. Since the information comes across the internet, the XM service functions best with AT&T's unlimited data plan.
