One of the more controversial changes made with the release of iOS 4.2 late last year was a change in the functionality of the switch on the side of the iPad, moving it from a screen rotation lock to a mute switch as seen on the iPhone. Apple CEO Steve Jobs had even reportedly responded to a customer question by noting that the change was permanent and that it would not be a user-configurable option.

Apple appears to have had a change of heart, as today's iOS 4.3 beta appears to have added an option in the device's Settings application to allow users to customize the behavior of the switch.
