If you’re not happy with Apple Maps on the new iOS 6 for iPhone and iPad, you can try Nokia Maps. You can now get it in full screen too. Officially, it’s currently a web app that needs the web browser. The address bar and the navigation tab take up space on the screen.
Thanks to Iain from Do It Different, he made a way for us to use the Nokia Maps for iOS in full screen. You just need to download and install the file from his blog directly on your iOS device.
