Since the moment the first iPhone was an-
nounced in 2007, there hasn’t been a more
talked-about technology product in existence.
The iPhone 4 is the best-selling smartphone
ever. It’s still alive and kicking, and now it’s
joined by the iPhone 4S. While it resembles the
iPhone 4, there are other delights in store: a
dual-core processor, upgraded camera, and
some brand-new voice-command technologies.
And let’s not forget iOS 5, Apple’s next version of its operating system
for the iPhone, iPod touch, and iPad.
That brings us to the subject of this book. Why would Macworld publish
an entire book about devices that are supposed to be so intuitive? It’s a
question I get a lot, even from people at Apple. After all, the company’s
goal is to make incredibly complex technology as simple as possible. And
these devices are easy to use, which is one reason they’re so appealing.
But make no mistake about it—your iPhone is a computer. It can run
thousands of apps written by independent developers, connect to Wi-Fi
networks, surf the Web, and check your email. You can make a video call
from the palm of your hand; you can even use your voice to give com-
mands, write text messages, and ask probing questions.
Apple may strive to make the iPhone easy to use, but it’s a device with
an ocean of depth. Our goal is to help you plumb those depths and
uncover more of your device’s hidden potential. In the pages of this
book, we’ll give the basics as well as advanced tips, tricks, and trouble-
shooting advice.

channel and our App Guide at Macworld.com.
