Two-step solution. First, rename the image you have by adding @2x before the dot (so pic.png becomes pic@2x.png). Then, make another image at half the pixel size of the first, and give it the original name. iOS 3 devices will use the new image, while iOS4 devices will see the @2x and use it instead.
