cherie, try this If VoiceOver is on and you want to turn it off from the device instead of from iTunes, remember that a double-tap acts like a single tap and you need to use three fingers to scroll when VoiceOver is on:
Press Home.
Tap Settings. Then double-tap Settings.
Tap General. Then double-tap General.
Use three fingers on the screen to scroll to Accessibility.
Tap Accessibility. Then double-tap Accessibility.
Tap VoiceOver. Then double-tap VoiceOver.
Tap "On" next to VoiceOver. Then double-tap "On" to turn it off.
You can configure the device to display options for VoiceOver, Zoom, or White on Black when you triple-click the Home button. This feature is off by default; to enable it, tap Settings > General > Accessibility > Triple-click Home.
If VoiceOver is on and the screen is black, but you can still use the device by pressing volume up and volume down, you may have screen curtain on. Try triple-tapping using three fingers on the device display to turn off screen curtain. Or connect the device to iTunes.
In iTunes
Connect iPhone or iPod touch to your computer.
In iTunes, select your device.
In the Summary pane, click Configure Universal Access in the Options section.
Select the accessibility features that you want to use and click OK.
