What resolutions should iOS graphics be?

What pixels per inch settings do iOS 4 graphics need to be to support the high resolution display? Should I just use the standard 72, or should I specifically make images that are 320x480@163ppi and 640x960@326ppi? Or, should I just make images those dimensions and not worry about the resolution (i.e. leave it at the default 72)?

I'm not concerned about the iPad, only iPhone 3/GS, iPhone 4 and iPod Touch users.

Note I realize this isn't about code, per se, but it is related to programming in so much as this is necessary for me to finish my iOS application ;)

326 ppi as that is the resolution of the retina display. They will resize/resample automatically on lower resolution displays.

Here is some more guidance:
