This part is where we show you what's under the hood and how to configure your iPhone to your liking. Then we look at the things to do if your iPhone ever becomes recalcitrant.

In Chapter 13, we explore every single iPhone setting that's not discussed in depth elsewhere in the book. iPhone offers dozens of different preferences and settings to make your iPhone your very own; by the time you finish with Chapter 13, you'll know how to customize every part of your iPhone that can be customized.

We love going on a shopping spree as much as the next guy. Chapter 14 is all about shopping in the App Store, an emporium replete with a gaggle of neat little programs and apps (more than 200,000 of them). Best of all, unlike most of the stores you shop in, a good number of the items can be had for free.

iPhones are well-behaved little beasts for the most part, except when they're not. Like the little girl with the little curl, when they're good they're very, very good, but when they're bad, they're horrid. So Chapter 15 is your comprehensive guide to troubleshooting for the iPhone. It details what to do when almost anything goes wrong, offering step-by-step instructions for specific situations as well as a plethora of tips and techniques you can try if something else goes awry. You may never need Chapter 15 (and we hope you won't), but you'll be very glad we put it here if your iPhone ever goes wonky on you.
