Google just released its popular Google Earth geographical software for the iPhone on Sunday, October 26, 2008. Google has jumped head-in to the world of iPhone apps with this very responsive, easy to use, and intelligent map app.
Google Earth is a free download, which is not surprising, as the PC and Mac versions are free as well. The iPhone version, unlike the full-fledged computer versions, do not have any advertisements built in (yet).

You may ask yourself, “What is the actual purpose of this application?” Well, I can’t exactly answer that - it’s mostly for exploring. It is helpful when wandering around a big city. It can also be useful in finding nearby places to eat, as Google Earth will put red pushpins on the map after you do a search. Although there are other apps like Urban Spoon that do a better job of this.
The auto locate feature was fairly accurate when I used it with my old generation iPhone. It was a few streets off, but pretty close. It would be more of a problem if I was lost and trying to find my way back. This feature should, however, work better with the newer iPhone 3G or 3GS.
