How to manage images (dimension-wise) in iPhone OS 3.1x / 3.2 / 4.0?

iPhone is 480 x 320, iPad is 1024 x 768, iOS 4 is 960 x 640. What is the good practice of managing images for 3 resolutions?

Say the app wallpaper as an example, the iPhone is probably a 50%-reduction of the iOS4 one. But it is also tempting to design one dimension (1024 x 768) for both devices (iPad and iOS 4 phones).

Any suggestions? thanks
