If you can't use a computer and iTunes, and need to navigate with Voice Over to turn it off, you need to remember that the gestures to navigate the iPad change.
For instance, to get to the Voice Over controls and turn them off when they are active you would.
Tap on the Settings icon (Says settings)
Double Tap (opens settings)
Tap General (tells you you've selected the General button)
Double Tap (opens General settings)
Tap Accessibility (sellects Accesibilty)
Double Tap (opens Accesibility)
Tap Voice Over (selects Voice Over)
Double Tap (Opens Voice Over)
Tap the On/Off switch (selcts the switch)
Double Tap (Turns Voice Over off)
(If you have to scroll to see something, use three fingers to swipe)
This seems overly complicated, but remember that a vision impared person can not see the screen well enough to naviate. They have to hear they've selected the right icon or controll first, then they can double tap anywhere on eh screen to activate it.
