iOS 4.3 Will Not Include Multitouch Gestures
It will not be enabled in iOS 4.3 for customers,we are providing this preview to gather input on how these gestures work with your apps.
Those who unaware of what multitouch gestures Apple added to iOS 4.3 beta, the company included several ways to jump between apps on the device.
Every uses either 4 or 5 fingers and allows you to swipe left and right on the screen to jump between apps.
Pinching the screen with 4 or 5 fingers jumps back to the home screen. It is believed Apple introduced these tests in 4.3 as a way to get rid of the Home button on iPad 2. The lack of home button would require these gestures to get back home.
Apple is dropping them in 4.3, we could see them in 4.4 or perhaps iOS 5 when it gets released.
