[gears-users] Question about 'radio_type' when using Geolocation API Network Procotocl

[Charles]

I have started experimenting with the Google Gears Geolocation API and
was successfully able to format a couple of JSON messages to the
server. I then start to pick a cell-id arbitrary. I was testing the
effect of the 'radio_type' parameter for GSM/WCDMA, these turns up
with the same location. I thought this was a bit strange because I
didn't expect the cell towers for different technologies to be
installed at the same location.

I also tried an invalid value for the 'radio_type', but it still came
back with the same result. Is there any way to tell if the API is
working correctly (ie. returning the correct expected location)?

Thanks,
Charles
