I didn't do a before/after comparison of the firmware in my Moment, during the upgrade to 2.1. But did a firmware update come along with 2.1, or was that strictly an upgrade of the Android software? Maybe there's something there, that would resolve the CDMA lockups that we sometimes encounter, since the 2.1 update didn't entirely solve the problem. Maybe we'll see an update from Sprint/Samsung. Maybe I'll win the lottery.
