In addition to the many features that make iPhone easy to use for everyone, accessibility features (available only on iPhone 3GS) are designed to make it easier for users with visual, auditory, or other physical disabilities to use iPhone. These accessibility features include:
VoiceOver
Zoom
White on Black
Mono Audio
Speak Auto-text
With the exception of VoiceOver, these accessibility features work with all iPhone applications, including third-party applications you download from the App Store. VoiceOver works with all applications that come preinstalled on iPhone. In addition, third-party developers can use the iPhone Accessibility API to make their applications accessible for VoiceOver users.
For more information about the accessibility features of iPhone, go to www.apple.com/accessibility.
Each accessibility feature can be turned on or off in the Accessibility settings on iPhone. You can also turn accessibility features on or off in iTunes when iPhone is connected to your computer.
Connect iPhone to your computer.
In iTunes, select iPhone in the sidebar.
In the Summary pane, click Configure Universal Access in the Options section.
Select the accessibility features that you want to use and click OK.
