In Settings, in General, then Multitasking Gestures, it says that you can use 4 or 5 fingers to "Pinch to the Home Screen". Well, it doesn't seem to work. When I'm on say, page 4, and do a pinch, it doesn't do anything. And I really don't know how to pinch with 4 or 5 fingers.... What does "Pinch to the Home Screen" mean? This gesture doesn't take me to the Home Screen.
