The screen annoyingly turns when I'm in bed.

[kaine]

So yeah, basically, when I lie on my side in bed, the screen will rotate to landscape, meaning I then have to hold the phone upside down or roll over to the other side.

I am a fat lazy cnut, and I can't be bothered to exit to the home screen to turn the accelerometer off with a widget.

Is there any such app that will turn this off for me after a certain time, and back on in the morning?

Edit: or an app that will have a toggle switch in the notification bar.
