I noticed in Sky magazine they are rolling out mobile checkin in select cities (ie using your device as your boarding pass), but as nothing works on my phone I don't think it will be that useful.

Funny, but some of the flight tracking apps on Itunes offer easier and oftentimes better flight info than the Delta mobile site.
