Technique works with Xcode 3, 4
Re-enabling experimental multi-touch gestures in the final iOS 4.3 firmware is a comparatively simple process, users point out. The beta firmware implemented special four- and five-finger gestures for the iPad which allowed people to jump to the homescreen, bring up the task switcher or swipe between apps. Even before the v4.3 gold master was introduced, however, it was known that the extra commands would not be enabled in public code by default.
To turn on the gestures, people must first download Xcode and connect their iPad. Any version of Xcode from v3 onwards should work. Selecting an iPad and then clicking the "Use for Development" button is the essential step; users are prompted for a developer account and password, but it's possible to hit Cancel without creating problems. Back on an iPad, people must toggle a "Multitasking Gestures" option in the General menu under Settings.
