With practice, you can learn to tell if the ringer is on while the iPhone is still in your
pocket. That’s because when the ringer is on, the switch falls in a straight line with
the volume keys. By swiping your thumb across these controls from front to back,
you can feel whether the silencer switch is lined up or tilted away.
Below the silencer, still on the left edge, is the volume control—an up/down
rocker switch. It works three different ways:
• On a call, these buttons adjust the speaker or earbud volume.
• When you’re listening to music, they adjust the playback volume.
• At all other times, they adjust the volume of sound effects like the ringer
and alarms.
Either way, a corresponding volume graphic appears on the screen to show
you where you are on the volume scale.
The Bottom and the Back
On the bottom edge of the iPhone, Apple has parked three important components,
none of which you’ll ever have to bother with: the speakerphone
speaker, the microphone, and, directly below the Home button, the 30-pin
connector that charges and syncs the iPhone with your computer.
