My Review
I've been using the "Sirius XM Online" iPhone app. It's very good with an easy-to-use and complete interface, it streams on both WiFi and 3G, the radio station songs update in real time, and the sound quality is great.
The only negative is that I have to pay an extra $36 per year for the online service. I would've thought that with lifetime subscriptions in two of the family cars that they would've thrown this in at no charge.
