Reading in Bed with iOS 4.2

iOS 4.2 on the iPad has changed some things. Most of them are good, but one is odd. There is a small switch on the right side of the iPad near the volume button. This used to lock the orientation of the iPad so it wouldn't rotate the picture when you rotated the iPad. This is good for reading in bed so if you lie on your side the picture stays correct for the way you're lilting, not for gravity. Well, that switch is now a mute switch. How do you lock orientation? Double-click your main button to bring up a menu bar on the bottom. Swipe to the left to find an orientation lock button. See instructions with pictures here
