Your being impatient. You only waited 35 minutes before bumping your own thread. Don't bump before it reaches page 2, and do some searching. There is a camera tricks demo out there.
you need to check the position of touch 1 and 2 when touched, then calculte the distance. Then have behaviors to interpolate or change the camera width and heigt depending on the distance between touches.
