The cool multitasking gesture, which appeared with iOS 4.3 beta will not be available with the consumer version of this iOS.
iOS 4.3 beta was released for developers last month, with new multitouch gestures, which allows users to use four or five finger gestures to pinch out of an app to the home screen and swipe up to reveal the multitasking bar. But consumers will not get this feature with iOS.
According to iOS 4.3 beta 2 notes:
“This feature will not be enabled in iOS 4.3 for customers, but we are providing this preview to gather input on how these gestures work with your apps.”
But experts expect this multitasking feature to come with future versions of iOS.
