How does iPhone resize images?
<p>Does iPhone automatically use bicubic resizing, or bicubic sharpening? </p>

<p>Say I have an image that will be 100 X 100 in the iPhone. I know I should make it 200 X 200 and append @2x.png so iPhone 4 high resolution screens can use that version. Assuming file size makes no difference (a huge assumption, I know)... would it matter if I just use a 800 X 800 image and let the iPhone do the resizing itself? Rather than me manually resizing a 800 X 800 image to 200 X 200? What different would it make?</p>
