I figured I'd go on ahead and kick this back to the top. I managed to find a QuickGPS thats slated for the Omnia that works and updates properly. However the display is messed up... (screen resolution differences?)...but its good enough to click the "download" button, and to get into settings and check the "auto update" box.

Hope this helps someone. Even though its not "pretty", it is functional in 6.5. Which is better than downloading the ephemeris file and moving it manually each week.
Cheers!
