You can find it on your i Phone simply by directing your browser here: As with all other web apps, you can create an icon on your main i Phone screen, simply hitting the bookmarks button (the “ ” sign in your browser).That feature allowed you to click a button on Google’s homepage and access the i Phone’s location services.

While you might think this would be extremely obvious, there is a big difference between Latitude and many of the other apps built for the i Phone: Latitude is entirely browser-based.

Yes, there is no native Latitude app, and there was some thought that since the mobile version of Safari on the i Phone can technically run in the background, that maybe it would allow apps like Latitude to also do the same. Unfortunately, since there is no mechanism for applications to run in the background on i Phone (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.

Pressing the “Locate” link on the right side of this page is obviously the easiest and fastest way to trace a mobile phone location — it’ll provide the map shown above, and you’ll know exactly where to go pick up your phone.

The option to lock your phone will provide the person who found your phone with a call button they can press (and a customized message you can write to them).

After we developed a Latitude application for the i Phone, Apple requested we release Latitude as a web application in order to avoid confusion with Maps on the i Phone, which uses Google to serve maps tiles.

That begs the question: Why not just have Latitude as an option built-in to the Maps application? And, if I really want to go out on a limb, I’m wondering if Apple wouldn’t allow Latitude running on Maps to eventually run in the background.

It’s a good idea to make sure you’ve enabled location services on your phone and provided Google with permission to trace your phone location.

This way, if it ever does get lost, you can quickly enable one of these features and protect your information.

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 so we very well could see Latitude stagnate in the same pool the other location-based i Phone services are in, because they cannot do location in the background.

Also, the lock feature alone could end up helping you retrieve your phone.
