I've gone through 2 N800s now, due to the get the Nokia screen, then the unit dies problem. With what little time I've used it, I don't want to give up so easily. I've reflashed both machines to the current version. Didn't work.
I'm returning the original unit, but still want to see if I can get the replacement working. Is it possible to reflash to an earlier version of the O.S.?
Thanks.

At least with the 770, one could download the update application and point it at a locally stored copy of the firmware. You could download all the different versions at Maemo.org
