Uncovered in the new iOS 4.3 beta released to developers today is a setting the restores the "lock screen orientation" functionality of the "mute" switch that was taken away iOS 4.2, Gizmodo reports. The control, originally created for iPad users, is now handled by a setting that allows users to choose whether to use the hardware switch for muting or for screen orientation. The change was unpopular with iPad owners, though orientation locking was still accessible via software.
