FYI, I don't know if anyone has posted this earlier, but I think the best method for transferring contacts over from WinMo to Android is to manually set up Active Sync on your phone to connect to GMail The following link shows you how to do this. Once you have, Active Sync keeps your contacts current with Google and Android keeps contacts current back the other way.
