Finally, Apple iPhone catches up with the rest of the mobile OS to have Google Latitude. However, it will not be available on the App Store. Instead, it will just be a web-hosted app that runs with Safari.
To use Latitude on iPhone, you will need to access your Safari browser and enter this URL.
I am not sure how it works with a browser. For example, on Windows Mobile, Latitude can have the option to keep track of your location even when the program is not running. If iPhone is using it as a browser app, won’t it be draining the battery of the iPhone?
Anyway, have fun with it because you will lose your privacy once you allow someone to track you.
