How do you move an app to another page?

You have to tap and hold the app (or any other app), the apps will start to wobble/shake on screen. You then hold and drag your app to the page you want on your iDevice. You will also in this mode see an X to the top right corner of the apps, this is used when you want to delete an app from your iDevice. Once you have finished moving your apps to the page/place you want them, then press the home button (the button with the square on it) and this will set all the apps as and where you wanted to place them.
