GottaGo is really worth a note! It is the first iPhone native app for public transportation in Switzerland. First it asks you for the start location and destination. It then gives you info about the commuter trains in the next 10 to 30 minutes which you thek can take. GottaGo incorporates the CoreLocation feature to find out your current location and shows you the nearest train stations. Fantastic!!

You cam download this application in the App Store or via iTunes.
