The iPhone 5 comes in a sleek little box, devoid of any documentation and if you downloaded iOS 6, you certainly didn't get a manual with it. For the most part that doesn't matter. One of the nice things about iPhones and iOS is that they're pretty intuitive. But not everything is obvious.
Aside from the widely reported flaws of Apple's new map app, it's also a bit confusing to use. It's pretty obvious how you search for an address or point of interest but once you find one or more, it's not necessarily clear how you get directions (hint: click on the little green car icon to the left).
There are also plenty of other tips on how to get the most out of the iPhone's camera, how to manage content on your iOS devices and other subjects that may not be quite as intuitive as others.
