I followed the link on the sirius.com website and downloaded the app - so it appears to be ready. It doesn't appear in the itunes store search yet.
There seems to be a glitch however as it wont install on my ipod touch ... "Application is not compatible with this ipod" - doing a factory restore now.
its official! check out www.yahoo.com it is the main ad on the right, sweet interactive
The app only works on the 2nd generation iPod touch which is kind of a let down. Anybody out there tried it on the original iPhone ?
