The Many Uses of the iPhone Home Button

By Sam Costello, About.com

Did you know that the iPhone’s Home button, the button at the bottom center of the phone, has more uses than just returning you to the phone’s default screen? It can also be used to control the iPhone’s phone and iPod features with just a few changed settings.

Home Button for Favorites

The first use of the Home button is as a shortcut to your phone’s favorites. With this setting, when you double-tap the Home button, your list of favorite people to call will be displayed.

Here’s how to set that preference:

- From the home screen, go to Settings
- In Settings, choose General
- In General, choose the second option, Home Button
- In Home Button, tap the option that reads Phone Favorites so that there is a checkmark next to it.

Now, each time you double-tap the iPhone’s Home button in quick succession, your phone favorites will appear.

Home Button for iPod

You can also use Home button to control the iPod feature of the iPhone. With this preference set, a double tap of the Home button will bring you right to your music – saving you clicks if you’re not at the home screen.

Here’s how to change this setting:

- From the home screen, go to Settings
- In Settings, choose General
- In General, choose the second option, Home Button
- In Home Button, tap the option that reads iPod so that there is a checkmark next to it.

Now, each time you double-tap the iPhone’s Home button in quick succession, your music list will appear.

Home Button for iPod Controls

In the same Preferences screen, there is also an option called iPod Controls. If you set the slider to “On,” a double-tap when the iPod is playing displays controls that offer the name of the song and pause/forward/backward buttons in a window overlaid on whatever program you’re using.

This gives you control of your iPod even while you are using other programs and allows you to jump to the iPod program.

Home Button for iPod Controls when Locked

Similarly, when your music is playing and the iPhone is locked, a double-tap of the Home button will display the iPod controls without unlocking the phone.
