If you had never seen all the videos and photos of the iPhone, and you just found it lying on someone's desk, you might not guess that it's a phone (let alone an iPod/Web browser/alarm clock/stopwatch/etc.). You can't see any antenna, mouthpiece, earpiece—and, goodness knows, there are no number keys for dialing.
It's all there, though, hidden inside this sleek black-and-silver slab.
For the rest of this book, and for the rest of your life with the iPhone, you'll be expected to know what's meant by, for example, "the Home button" and "the Sleep/Wake switch." A guided tour, therefore, is in order. Keep hands and feet inside the tram at all times.
On the top edge of the iPhone, you'll find a black plastic button shaped like a dash.
This button has several functions.
Sleep/Wake. Tapping it once puts the iPhone to sleep—that is, into Standby mode, ready for incoming calls but consuming very little power. Tapping it again turns on the screen, so it's ready for action.
On/Off. This switch can also turn the iPhone off completely, so it consumes no power at all; incoming calls get dumped into voicemail (Visual Voicemail). You might turn the iPhone off whenever you're not going to use it for a few days.
To turn the iPhone off, press the Sleep/Wake switch for three seconds. The screen changes to say, "slide to power off." Confirm your decision by placing a fingertip on the red right-pointing arrow and sliding to the right. The device shuts off completely.
Tip
If you change your mind about turning the iPhone off, tap the Cancel button, or do nothing. If the iPhone decides that you're not paying attention, it dismisses the "slide to power off" screen automatically.
To turn the iPhone back on, press the switch again for one second. The chromelike Apple logo appears as the phone boots up.
Answer call/Dump to voicemail. The upper-right switch has one more function. When a call comes in, you can tap it once to silence the ringing or vibrating. After four rings, the call goes to your voicemail.
You can also tap it twice to dump the call to voicemail immediately. (Of course, because they didn't hear four rings, iPhone veterans will know that you've blown them off. Bruised egos may result. Welcome to the new world of iPhone Etiquette.)
When you don't touch the screen for one minute, or when you put the iPhone to sleep, the phone locks itself. When it's locked, the screen isn't touch-sensitive. Fortunately, you can still take phone calls and control music playback.
Remember, this phone is all touch screen, so it's much more prone to accidental button-pushes than most phones. You wouldn't want to discover that your iPhone has been calling people or taking photos from the depths of your pocket or purse.
That's why the first thing you do after waking the iPhone is unlock it. Fortunately, that's easy (and a lot of fun) to do: place your fingertip on the gray arrow and slide it to the right, as indicated by the animation.
Tip
The iPhone can demand a password each time it wakes up, if you like. General.
