The Home screen displays all your installed and preinstalled apps and gives you access to your iPhone settings. No matter where you are or what you’re doing, push Home and you’re back at home base.
You can also double-tap the Home button to pull up a scrolling list of apps so you can quickly move from one to another.
On/Off button: You can use this button to power up your iPhone, put it in Sleep mode, wake it up, or power it down.
Dock connector slot: Plug in the Dock Connector to USB Cable to charge your battery or sync your iPhone with your computer.
Cameras: The iPhone 4 and 4S offer front- and rear-facing cameras that you can use to shoot photos or video. The rear one is on the top-right corner, and you need to be careful not to put your thumb over it when taking shots.
Ring/Silent switch: Slide this little switch to mute or unmute the sound on your iPhone.
