Using the settings/software/new path, I found there was a new update for my Fascinate available. It installed fine on my Fascinate. On my wife's it was slow (and it said it downloaded in the background) and after a while I hit back buttton....... MISTAKE!!!!. I now know what a bricked phone looks like (I took it into verizon and a new phone is on its way).
The update goes from EDO1 to EDO4. I guess that means a minor update for 2.2.1. Haven't found what the improvements are yet but I'm looking. I'll post when I find them.
Good luck and WAIT for the update to take place
