Just checked the threads over at geekstoolbox and it sounds like nothing has changed. The app is still complete, but (reading between the lines) it appears that they haven't received permission from Sirius to publish it. The moderator told people the app is done and if we want to see it, we should write to sirius to request their support.
I am so sick of Sirius and their small thinking ways. I am one of the people with XM and Sirius subs and Sirius has also been inferior in terms of technology, sat coverage (which SUCKS compared to XM), narrow playlists, uninformed DJs leftover from their FM days, etc... They even managed to botch the feed they send to Sonos users as it has been broken for a few weeks now. They just don't get it.
SiriusXM could partner with the nicemac/geeks folks and have a huge hit on their hands since their business should be about generating subs, not selling consumer electronics, especially with the auto market tanking and their stock trading at $.20 and facing delisting. I am sure they will ultimately relent, unless they are cooking up their own (likely paid) app.
Maybe uSirius will beat them to the punch since his app worked great on my jailbroken phone.
