Change Function of Mute Switch back to Lock Rotate on iOS 4.3
While you are playing around with the new iOS 4.3 beta on the iPad,we came hear with an interesting menu item in the settings app. now you now change what the Mute button does. You now have the option of switching it back to a lock rotation button.
When the iPad first got iOS 4 the handy lock rotate button had its function changed to a mute switch. Since then, to lock the rotation you had to double tap the home button, swipe to the controls menu and then tap the orientation lock button.
The switch back and forth is as simple as jumping in to the General Settings menu and selecting which option you want, You can seen it in the image below.
