Among the biggest changes in Version 2.0 of Google Earth is the ability to view custom maps stored in the "My Maps" section of users' Google Maps accounts.
By logging in directly to your Google Maps account, you can view the same maps that you or others have created, using the My Maps interface. Maybe you're on a trip and want to see where Tony Wheeler, the co-founder of Lonely Planet, most likes to travel. Or perhaps you're walking around looking for a restaurant and you want to see where world-famous chef Ferran Adri likes to eat. All you have to do is click "Save to My Maps", open Earth on the iPhone, log in with the same account information, and voil, you have your same collection of My Maps right in your pocket.
