I've got an Iphone, and from what I understand, there is a SiriXM player app in development, and I think there is already a mobile player app for WindowsMobile? For those of you with either of these, how exactly does it work? How are you charged for the time you use it? Is the time of use considered part of your data plan? How's the sound quality and easy of use of these apps?
