How can I get Google Maps on iOS 6?
You can still use Google Maps on iOS 6. Although reports have differed over whether or not Google is working on a stand-alone Google Maps app that would be released on the App Store, using Google Maps is possible right now.
iOS 6 users should open their web browser and navigate to maps.google.com. The Google Maps web app will ask to use your current location. To save Google Maps to your home screen, in Safari tap the share button at the bottom center of the screen (with the arrow and box). Then tap Add to Home Screen.
Enter a name for the shortcut or leave the entry as "Google Maps" and tap the Add button. From now on, you can immediately launch Google Maps from the home screen.
