How to lock iPad Orientation for iOS 4.2

The first thing I’ve noticed after updating my iPad OS to the new iOS 4.2 was the missing button for the rotation lock on the iPad. The rotation lock on the iPad has moved with iOS 4.2 — it has become a mute switch. To lock orientation of the iPad, double-click the Home button on the front of the iPad and a new tray will appear at the bottom of the screen. Slide the multitasking tray to the right to reveal a rotation lock, volume and brightness controls and iPod playback controls.

Click the rotation lock button to change the orientation of the iPad — the button at the left toggles your screen lock on and off.
