Last week we posted on Google's Latitude service coming to the iPhone by way of Safari. Of course, as Computerworld (via MacRumors) points out, for the location-tracking buddy service to work in the browser, the browser must support geo-location, and not just for Google.

According to BrowserSphere developers were told back in March that Safari would support the Geolocation JavaScript classes, which "work with the onboard location services to retrieve the current location of the device."

So we guess IP addresses won't be the only way for annoying web ads to try and localize us any more?
