iPhone 3G S provides new accessibility features including VoiceOver, a screen
reader that speaks what appears on the iPhone 3G S display, enabling visually
impaired users to make calls, read email, browse web pages, play music and run
applications. The new universal Zoom function magnifies the entire screen, and
the White on Black feature reverses the colors on screen to provide higher
contrast for people with low vision. iPhone 3G S also supports Mono Audio which
combines left and right audio channels so that they can be heard in both earbuds
for those with hearing loss in one ear.
