Apple recently put up instructions on its site explaining how to add a web app to your iPhone’s home screen. Although they use their own site as the example, they prompt the instructions with this sentence:
“For fast, easy access to Google and Nokia maps on the web, simply add their sites to the Home screen of your iOS 6 device.”
So in four easy steps you can once again enjoy the beauty that is Google Maps, for the most part. Their web app does lack a few minor features found in the built-in app.
