Apple plans to replace Google Maps with its own 3D mapping software when it releases iOS 6 this fall, but Google has beaten them to the punch by adding a new 3D view to its Google Earth app.
Verison 7.0 of Google Earth features 3D imagery for 14 regions including: Los Angeles, Boston, San Francisco, Geneva and Rome. Google plans to add additional 3D cities to the iOS and Android platforms in the coming weeks. Version 7.0 also allows you to explore various locations, historic landmarks and natural wonders with its new "Tour Guide" feature. The new 3D view is available for the iPhone 4S, iPad 2 and new iPad. You can download the app for free from the Apple App Store.
