Accelerometer Lock

Some iPhone applications have preferences to set an accelerometer lock under Settings. When rotation is disabled, the orientation of the app stays fixed in one direction no matter which way the iPhone is turned.

Most commonly used apps such as Safari, Messaging, Mail and iPod do not have this feature available in the preferences. In contrast, orientation can be temporarily fixed when viewing photos on the iPhone Camera Roll or Photo Library.

Rotation can be switched off when viewing photos on the iPhone Camera Roll or Photo Library. When viewing a photo, hold down with one finger on the photo as if you're trying to copy the image.
