Want to make moving all those apps on your iPhone or iPod touch from screen to screen easier? Why not move your four dock applications: Phone, Mail, Safari and iPod (or, on the iPod touch, Music, Videos, Photos and iTunes)?
By moving one or several of them temporarily to another screen, it’s much easier to move multiple apps around. Just drag them to the dock (which stays constant regardless of what screen you’re on); you can use the dock as a sort of “shelf” that will hold the apps while you switch screens. This is much easier than dragging an app to a given page of your home screens.
