Google Latitude for iPhone
A good news for iPhone lovers: Google latitude is now available for their devices. With google latitude, you can view the current location of your friends and you can share the messages with them.
You’ll also find basic Search and Directions functionality to help you get around the world. And just like our Google Maps for mobile client apps, you can press the “blue dot” to be taken to your approximate current location on the map with My Location.

To try Google Latitude, type google.com/latitude into your iPhone’s browser. And if you miss the experience of launching the app directly from your home screen, you can add a bookmark to the home screen by opening Latitude in Safari and tapping the + icon > Add to Home Screen > Add.
The Google Latitude web app currently supports iPhone/iPod Touch OS 3.0 or above. For now, it’s available in the US, UK, Canada, Australia, and New Zealand, and it will be available in more countries soon.
