The iPhone screen size is 568 x 320 in landscape mode. What you need to remember is you need to double the size for Retina display so if your making a background that you want to be the size of the screen and no more, make it 1136 x 640 and it will then be Retina ready. You need to do this with all graphics. What ever size they are in GS, double it when creating them! Hope that answers your question and makes sense.
