I'm waiting for the official push. I know that "901" was obtained from an accidental/intentional VZW push and that everyone seems to like it, but still there is no guarantee that they won't find something that needs to be fixed - leading them to bump the release number, and potentially stranding "901" users off the upgrade path. For example, a "945" release might not bother to recognize "901" as a valid version to upgrade from. It should, given that they sent "901" to some, but again no guarantee. Last year, Thunderbolt users got a pre-release and some bricked their phones, requiring replacement. Different situation, but demonstrates that installing pre-releases is not without risk. If "901" is as good as they say, it should start pushing any time now...
