In accordance with some embodiments, a computer- implemented method is performed at a portable multifunction device (100) with a touch screen display (112) and one or more accelerometers (168). The method includes displaying information on the touch screen display (112) in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers (168). The method also includes detecting a predetermined finger gesture (4402) on or near the touch screen display (112) while the information is displayed in a first view, and in response to detecting the predetermined finger gesture (4402), displaying the information in a second view and locking the display of information in the second view. The method further includes unlocking the display of information in the second view when the device is placed in an orientation where the second view is displayed based on an analysis of data received from the one or more accelerometers (168).
