Google has updated their Google Earth app for iOS to add three-dimensional imagery to major locations including Washington D.C, San Francisco and Boston.
It’s arriving alongside Tour Guide; select a notable attraction to go straight to it, with accompanying trivia you can bore your friends with later. Sadly 3D maps requires the processing hardware of the iPhone 4S, iPad 2 or the third-generation iPad, but other iOS (4.2 or higher) device users can still get access to Tour Guide.
Google Earth is available for free in the app store…
