Has anyone else checked out mobile.delta.com today? It appears that they have added back many of the features that were disabled after the FF program integration, including the ability to see itineraries and view/book flights. I haven't looked into mobile check-in because I don't have a flight in the next 24 hours, but it appears they have made some movement back in the right direction here.

For what it's worth, I'm using a BlackBerry Curve, but I can get it to pull up using Google Chrome on my computer too.
