I’ve installed Google Latitude on my HTC Touch HD, which came packaged as a new version of Google Maps, and can now see myself labeled on the map. Hoorah. Now all I need are a view friends with it installed.
One issue I can see, though, is that it does not seem to be updating my location in the background, if the blue dot on the map is anything to go by. I have to make Google Maps the foreground application for it to re-determine my location. Maybe the Android version works better.
