Frozen Zune 30s

At shortly after midnight last night, thousands of Zune 30s inexplicably froze up. They are currently stuck on the boot-up screen, shown above.
Our forums have been deluged with reports of this, as has Microsoft’s zune.net forums.
We’re awaiting on an official fix from Microsoft, and will report it here as it surfaces.
Some have reported success by letting the battery die and rebooting their 30s. Other less patient, or more adventurous people, have removed and re-inserted their batteries. But others are reporting that the players revert to the frozen start-up screen afterward.
My advice; don’t turn on your Zune 30s until we get a ‘fix’ from Microsoft. A solution is no doubt in the works. Stand by!
Update: my Microsoft MVP contact has emailed me to confirm that the Zune team is attacking the problem. I expect I’ll get further progress updates by email. Will post them here.
Update (2pm Pacific): Getting generally encouraging signs from the Zune team, and they are definitely “on it”. Will post more when I can.
Thanks to gab0 for the pic! And to Bond007 for being the first to report it in our forums.
