AeroPod, PowerPod and Newton

I know i have seen the diagram before for installing/placement of the foam rails. I upgraded my Iphone 4 from 3gs. Does anyone know if the diagram is on the idash page, if not where is it located? .....Thanks.......jim beauregard

Remove the old rails, then attach the new rails where the old ones were, making sure that the curved ends of the rails line up with the curved ends of the tray.
