3. In the Devices list in the Source list, click the entry for the iPad or iPhone to display its control screens.

Moving an App to a New Position on the Same Home Screen
To move an app to a new position on the same Home scree, click the app and drag it to where you want it to appear. The other apps move out of the way to make room for the app you’re moving.
Moving an App to a Different Home Screen
To move an app to a different Home screen, follow these steps:
1. Click the app and drag it to the list of Home screens and hold it over the Home screen to which you want to move it. iTunes displays that Home screen.
2. Drag the app to where you want it to appear, and the drop it. The other apps move out of the way to make space for the app. If the Home screen is full, the last app gets bumped off it. If the next Home screen has a free space, the app lands on the that Home screen; if the next Home screen is full, iOS creates a new Home screen and puts the app there all on its lonesome (until you rearrange that apps further).
You can customize the main apps at the bottom of the Home screens. Click one of the main apps and drag it off the bar at the bottom of the screen. Then click and drag there app or folder you want instead.
