Google is bringing cities into full 3D view in the latest update on the Google Earth iOS app. Available for the new iPad, iPad 2 and iPhone 4S, the app gives a full tour of city streets in a handful of cities across the U.S. and Europe.

Check it out: “A map must be comprehensive and accurate no matter where you are or what device you use. We also believe maps can be useful in ways you might not have imagined. With today’s release of Google Earth for iOS you can literally fly through breathtaking 3D city landscapes and images and follow virtual tours of places you’ve never been — all with a simple swipe of your fingertip. It’s a new, and I think magical way to explore the world in which we live.”

Cities that have gotten the 3D Google treatment include Boston, Portland, San Diego, San Francisco, Los Angeles, and even Rome, Italy. Follow this link to take a tour.
