Here you will get new release Lock the screen rotation with iOS4 firmware update includes a rotation lock feature, similar to the rotation lock switch found on the first generation iPad.
The iOS4 update for my iPad, i noticed that the screen-rotation lock button has changed to the mute button. If you are not aware of what i’m talking about, it’s the one right next to the volume control button on your iPad.
Pressing on we will see the words "Flip Locked" or "Vertical Orientation Unlocked", going back to press.
