From The Motley Fool: "In news broken by unofficial Apple blog TUAW last night, Sirius XM has been sending out emails to satellite radio fans who have requested information on the upcoming application. The missive claims that the official Sirius XM program for iPhone and Wi-Fi-tethered iPod touch owners will be available tomorrow. Not so fast, though. The program won't be freely available for most of Sirius XM's 18.6 million subscribers. Streaming through Apple's devices will be limited to premium Sirius or XM Internet radio subscribers. Those are the accounts without satellite receivers who pay $12.95 a month for Web-only access or satellite subscribers who pay an additional $2.99 a month for premium online playback." Sweet.
