You and Your iPhone 4S . . .

This is the heart of iPhone 4S Made Simple. In this section, you'll find clearly labeled chapters—each explaining the key features of your iPhone. You'll see that most chapters focus on an individual app or a specific type of application. Many of the chapters discuss applications that come with your iPhone, but we also include some fun and useful apps you can download from the App Store. Sure, the iPhone 4S is for fun, but it's for a whole lot more, too. We finish with some handy troubleshooting tips that can help if your iPhone isn't working quite right.
