Well, I just tried my old code from my n800 and I had removed the license from it and it doesn't work on my n810...that's real nice.
So I figured I'll order a new version and give my n800 to a colleague, and it sat at the "Waiting for purchase confirmation" screen indefinitely.
Real nice, I canceled it and restarted the map app, and it seems to have worked fine...
Then there is the map upgrade that is available that says "it is likely to harm the system" even better given the installed and updated version are the same version!
