Google has [optimized its Google Latitude](http://googlemobile.blogspot.com/2009/07/google-latitude-now-for-iphone.html) for the Safari browser in iPhone and iPod touch. Google Latitude is a web application and requires iPhone OS 3.0 as the mobile Safari browser in this version of iPhone OS can feed back the device’s location to web application.

For the iPhone version of Google Latitude, you get basic Search and Directions functionality. However you need to fire up Google Latitude to keep your location updated to Google’s backend server since Google Latitude can not run in the background, just as any other non-Apple apps.
Unfortunately, since there is no mechanism for applications to run in the background on iPhone (which applies to browser-based web apps as well), we’re not able to provide continuous background location updates in the same way that we can for Latitude users on Android, Blackberry, Symbian and Window Mobile. Nevertheless, your location is updated every time you fire up the app and then continuously updated while the app is running in the foreground. And, of course, you can check in on where your friends are, so we think there’s plenty of fun to be had with Latitude.
Google is launching Latitude for iPhone in US, UK, Canada, Australia, and New Zealand at the moment, with more countries coming soon.
To visit Google Latitude, point your Safari browser on your iPhone or iPod touch to
