There is one additional feature that the owners of iPhone 4, iPhone 3GS, iOS 4.3.1 mobile devices can use on these smartphones(from the one and only tech giant Apple) – the Multi-touch gesture.

What’s the Role of this Multi-touch Gesture?

Apple released iOS 4.3.1 with an hidden presence of multi-gesture touch, to do with 4 and 5 fingers to run their application without using the Start button. Multi-touch gestures provides the ability to exit an application and return to the home screen by pressing with four or five fingers.
