I downloaded and run
The penelope has 3 types of Camera Setup
May I ask does it has 2D Gameplay Camera Setup for unity iphone?
Moreover, I read http://unity3d.com/support/resources/tutorials/video-animation-view
But, it is more simple in unity iphone, does it use the same concept?
For 2D set your camera to Orthographic. That means the camera doesn’t have any perspective, it is looking at every pixel from the same angle.
Have your camera pointing along one axis, for example Z. Then set up your game on the other 2 axis. In the example, X and Y.
This does not give you 1 pixel on a texture to 1 pixel on the screen. My way would be to create a 480x320 image, then set the Orthographic Size so that the image exactly matches the screen. Someone else may know a better way.
