The Sirius XM iPhone app requires a $3/month subscription, but it's missing a few notable channels. From the company: "Some select programming, including MLB® Play-by-Play, NFL Play-by-Play, SIRIUS NASCAR® Radio, and Howard Stern, will not be available on the iPhone and iPod touch. Listeners will continue to be able to access that programming through the platforms they are currently offered on." We can understand removing any semblance of premium content from the service, but ending a sentence in a preposition is unforgivable. [iPhone Savior and Modified Logic]
