The first firmware update seems to have been release, but I can't get my unit to update for the life of me.  It recognizes there's an update and will initiate the process, but keeps shutting off during the update process and tries to restart the process when it powers up again.  I remember reading something earlier about issues with firmware updates in areas with low GSM signal so I tried bringing it to work where my phone usually gets 4 or 5 bars.  The update process bar gets around 20% through and the system seems to shut off suddenly with no activity after letting it sit for 20 minutes or so.
