Google has released “Google Latitute” and is available in 27 countries including Canada and 42 languages. Currently available on Android, Blackberry, Symbian S60, and Windows Mobile (iPhone soon).
Google describes this as a “feature of Google Maps for mobile that allows you to share your location with your friends and to see their approximate locations, if they choose to share them with you”. It’s the ultimate tracking device that allows you to keep track of your friends… you can also call, SMS, IM, or email each other within the application.
From your mobile you visit www.google.com/latitude to download the app. Video demonstration here:
