It seems the Palm Pre GPS was never tested in the southern hemisphere – my new Pre’s GPS reports Lat: 394.6, Long: 138.6

The latitude value should be 34.6 degrees South (or -34.6 degrees).
That would explain why Google Maps isn’t working.
Now I need to work out how to replace the Coordinates java class in /usr/lib/luna/java/location.jar, so that the getLatitude method returns a number between -90 and +90 …
I wonder how many WebOS applications will then barf on a negative latitude value …
