When you install new apps to your iPad, the system stacks up the icons automatically without asking you to select a home screen. But you can subsequently re-arrange the icons on the home screens and on the Dock.

1. Touch and hold any icon on your screen until the icons start wiggling.
2. Drag an icon to a different spot on the screen, or even to or from the Dock, which allows for six icons.
3. You can also drag an icon to the left or right edge of the screen until it starts sliding, then drop the icon to another screen.
4. Click the Home button to finish.

Enjoy!
