Latitude;
Google Latitude is the back bone to my location app. Its a service that rinsed in the background on your mobile, updating your current location per the phone gps.
Warning: if you use this make sure that you have unlimited data plan.
There are two main problems with latitude:
a) it does not remember where you have been, only showing the real time location; and
b) there is no manual over ride on the frequency with which the location is updated ... google give a blurb about power management on mobile devices as an excuse for the absence of this feature.
Another useful Link:
javascript:void(prompt('',gApplication.getMap().getCenter()));
Copy-paste this in you browser when you are at google maps and it will give to the latitude and longitude of the location at the center of the screen. A useful tip of getting the lat/lon position is to right click on the map and select 'center map' option.
Tech;
The google API for those interested can be found here and there are plenty of good examples flying around in their documentation.

Once you get a hang of it, its a little bit addictive ... I am so hooked !!
