Mike, who'd previously let us know about that leaked out 6.1 update has been watching Motorola's site like a ravenous hawk hovering over a field mouse. That mouse has finally popped out of its hole: head on over to Motorola's site for the official Motorola Q9h 6.1 Update.
You're going to need the standard complement of update tools before you get going: Windows XP or Vista, internet connectivity (the software just might be calling home to check to see if your Q9h is legit), and a full backup before you update. Like all ROM updates, this one will wipe your device, so get prepared.
Welcome to the sliding panel glory of Windows Mobile 6.1 on the Q9h everybody. I've been in here for awhile, and let me tell you: jump on in, the water's fine.
Download the installer directly here. Thanks, Mike!
