Great article, this is what I was looking for, Iphone touchscreen events
# flash.events.TouchEvent when the user touches the device. Unlike the click of a mouse, up to five touchEvents can be detected simultaneously. For that reason, each touch is assigned a touchPointID along with its x and y coordinates. The amount of pressure applied can also be measured.
# flash.events.GestureEvent captures familiar gestures on the device such as pinching, zooming in and out.
# flash.events.AccelerometerEvent displays updates from the device accelerometer sensor. It works with x, y and z axis to detect movement in space.
# flash.events.GeolocationEvent displays updates directly from the device location sensor. It contains latitude, longitude but also altitude, speed and heading (compass movement).
# flash.events.StageOrientationEvent displays orientation updates including right, left and upside down. Your application can be initialized as a specific orientation (landscape or portrait) then ignore orientation change.
