Have you heard? No Google maps app on Apple iPhone's iOS6. Yep. That's right. This makes sense for Google, of course, because Google is in competition with Apple. Basically Google is saying, "Hey, competitor, make your own mapping app." While the Google maps app is not available for the iphone, there is a workaround so don't despair. No, it's not the app, but it's still google maps.
Go to Safari. Type in Google in the address bar. Once you're there, click on "maps." You might be asked by the browser if you'd like to add a shortcut icon to your home screen. Do it and now you'll be able to access Google maps on your newly updated iphone. No, it's not perfect and accessing Google maps through the web isn't as fluid as the app version; however, currently, this is the only way to use Google maps on your iOS6 smartphone.
