Google Earth for iPod Touch

Google has recently updated to Google Earth 2.0 for the iPod touch. (It is also available for the iPhone). Google earth is an awesome application, and it is the closest thing you are going to get to a free GPS app for the iPod Touch. If you have GPS support, the app will actually show you where you are in 3D surroundings. You can look at satellite view or street map, and you can even zoom in to street view so that you are looking at houses and buildings from eye level. You can even use this app to route travel, great for car trips and vacations.
