Google Latitude available in iTunes

Google has just released a new app for the iPhone, iPad and iPod Touch. Latitude is an app which allows you to track the location of your friends. It uses iOS4 multitasking to run in the background and constantly broadcast your location to all your friends. I'm not sure many people would be keen on this app and while it would be really useful sometimes, such as when you're meeting friends, a lot of the time it could be seen as a simple invasion of privacy. There are options to hide your location and also manually set a location which could lead to some interesting suprises...
