Hi,
It seems like you are trying to access Google location server directly. I'm
afraid this would violate the Gears Terms of Service. Direct use of the
server using the JSON protocol is prohibited. See section 5.3 of
http://gears.google.com/tos.html
You can only use the Google location server through the Gears JavaScript
Geolocation API. See http://code.google.com/apis/gears/api_geolocation.html.
We publish the JSON protocol to allow third parties to implement their own
server, which Gears can then be configured to use instead of the default
server provided by Google.
Hope that helps,
Austin
