Just over a year after the application's launch, Google has announced an update for Google Earth for the iPhone and iPod touch.

With the original at one point the second most-downloaded free application overall, it's an update that will likely be downloaded by a fair few users.

Version 2.0 of Google Earth for iPhone adds the ability to view maps created or saved on a desktop computer on an iPhone via the MyMaps settings, improved icon selection and performance and the availability of the app in new languages.

The app will be rolling out around the world over the next day or so, available to download for free from the iTunes App Store.
