Where to Go from Here
If you’re new to iPhone, closely read the first few chapters to get an understanding of how your iPhone works, the command conventions it uses, and how to perform the basic functions. Then move on to chapters that interest you, perhaps starting with the phone and messaging functions before moving up to Internet access, and lastly looking at the multimedia apps like Music, Podcasts, and Camera.
If you’re familiar with your iPhone already, skim through the opening chapters to learn about the recent iOS 8 changes, and then go where you want – for example, to a chapter on a function you haven’t used before, which might be the new video camera functions or Health, or to a function you use a lot but would like to know better, such as Messages.
No matter where you begin, our goal is to give you the tools to get the most out of your iPhone and encourage you to expand your knowledge and explore the many ways of iPhone.
Book I
Getting Started with iPhone
Chapter 1
Exploring the Many Faces of iPhone
In This Chapter
▶ Taking a look at the hardware
▶ Considering iPhone carriers
▶ Making phone calls
▶ Sending messages
▶ Surfing the web
▶ Taking photos and videos
▶ Entertaining yourself with apps
The more you use your iPhone, the more you discover how powerful it is and how many handy, helpful things it can do. We know people – and you probably do, too – who resisted the iPhone craze and then, after having had an iPhone for a week (or a day), never leave it out of arm’s reach.
In this chapter, we try to pique your curiosity about things you may not have thought of doing with your iPhone by introducing you to all your iPhone can do. We talk about the hardware, review your cellular carrier options, and summarize the apps that come with your iPhone. You can then pick and choose the topics and tasks where you want to dive deeper and go to those chapters for the details. We’d like you to think about how you can incorporate your iPhone into your day-to-day activities but don’t worry: We don’t want technology to take charge of your life. We want you to take charge of the technology.
Looking at Your iPhone from Every Angle
With the release of iPhone 6, iPhone models come in different sizes, but the overall function of each model is the same. Here we take a look at the hardware and give you a closer look at what’s inside.
Front, back, top, bottom
This book explains how to use iOS 8, the latest iPhone operating system. iPhone models 4s or later work with iOS 8. The iPhone screen and body materials vary slightly from model to model, but rest assured that each is scratch- and shatter-resistant, although that doesn’t mean they’ll survive a beating with a hammer or being dropped from a sixth-floor window.
A metal band around the edge of the iPhone (which you may or may not see, depending on the model) not only gives stability and structure to your iPhone, but also functions as two antennae. In addition to the antennae, the buttons and holes around the edges and on the front and back, which we explain in detail in Book I, Chapter 2, have the following functions:
✔ Sleep/Wake button
✔ Microphones
✔ Lightning port for connecting various cables and connectors (Dock connector on 4s)
✔ Volume buttons
✔ Silent/ring switch
✔ Two video/still camera lenses
✔ LED flash/light or dual LED True Tone flash/light
✔ SIM tray
✔ Speaker
✔ Headset jack
✔ Home button (with fingerprint sensor on iPhone models with Touch ID)
What you don’t see can help you
Your iPhone has antennae and sensors to support the functions of the apps you use. One antenna is the metal band around the outside that connects to the cellular network. The iPhone actually switches between two antennae to receive and transmit, which increases data transfer speeds and call quality. Here’s what those visible and not-so-visible parts do:
✔ GPS and GLONASS: Finds your location, gives you directions in Maps, and geotags your photos. In Book IV, Chapter 1, we explain how geotagging identifies your location when you take a photo.
✔ Wi-Fi: Connects to available Wi-Fi networks.
✔ Cellular antenna: Connects you to a selection of the following networks: LTE, GSM/EDGE, CDMA EV-DO, UMTS/HSPA +/DC_HSDPA, 2G, 3G, or 4G networks. We explain the different types of cellular networks, and what all these nerdy terms and acronyms mean, in Book I, Chapter 2.
✔ Three-axis gyroscope: Used to find your location when GPS or GLONASS aren’t
