I was wondering if anyone who has upgraded to 4.2 has verified if the audio from the Sirius app would play properly through AirPlay? My wife loves a couple of the channels, and I'm thinking about adding a subscription to the internet version for her. I have an Airport Express in the living room, so it would be perfect if she could use her iPhone to play the audio through that. It's a long shot, but it seems like something that could be possible. Thanks!
