Like a few, this update went off without a hitch. Using the Vista version and undocked laptop with the USB cable only, I followed their directions. Downloaded and updated the modem driver manually so when the update started, it recognized the necessary SW updates as complete. I also hard reset the device after unchecking the USB box in connection settings and reattaching the cord before starting Step 5. I had to resync all the Outlook and reload 3rd party programs, but much better than continually repeating steps as when I upgraded the 730 to WM5.

Good luck...
