Retina Images

I watched the tutorial by Cheetomoskeeto on youtube and I’ve got a question. What if I want to place my image at x: 137, y: 208. What should I add in the coordinates?

ball.x = \_W + 137  
ball.y = \_H + 208?   

Wouldn’t that make it wrong when testing on both the iPhone 4 and iPhone 3GS?
