iPad home screen not rotating

Check your side switch settings. See the following:

http://support.apple.com/kb/HT4085

In that case, try to reset your device:

Device Reset (won't affect settings/data/music/apps/etc)

1. Press and hold (& continue to hold) BOTH the Sleep/Wake button & the Home button.

2. Continue to hold BOTH (ignoring any other messages that may show) until you see the Apple logo on the screen.

3. Release BOTH buttons when you see the Apple logo and allow the device to boot normally.

Thanks! I had the same problem with my home screen and your advice worked.

Thanks - worked for me too!
