Answer 1

If you're designing your own interface elements and need image dimensions, yes; you just double the values. However, in your code, when referring to the coordinate system of elements (points), you still use then 320x480 point system, as the points are automatically scaled for different device resolutions.

For images, the retina sized images must have the same file name, but with @2x following. For instance, background.png (320x480) must have a similar image [email protected] with dimensions 640x960.
