Google has shown off their Google Latitude running on the iPhone OS 3.0 Safari browser, and we have the video for your viewing pleasure below.

Google Latitude is a real time friend tracking service and the video shows just how well Google Latitude plays with “W3C” geo-location API

This means the iPhone OS 3.0 will allow the Safari web browser to determine the iPhoner’s location and use said info to update location aware services such as Google Latitude and thus paves the way for turn by turn GPS navigation. Hit up the video and enjoy.
