Try a soft reset first:

1. Press and hold the Sleep/Wake button on the top of the unit until a red slider appears

2. Drag the slider.

3. Press and hold the Sleep/Wake button until the Apple logo appears.

If a soft reset doesn’t work, try a hard reset:

Press and hold both the Sleep/Wake button and the Home button for about ten seconds, until the Apple logo appears.
