Does Apple scale down iPhone 4 resolution screenshots for iPhone 3 on your app page?

When I'm submitting my iOS app, there's a place where I can upload screenshots under the heading "iPhone and iPod Touch sc开发者_StackOverflow中文版reenshots". If I upload an iPhone4 960x480 screenshot, will it be excluded from iPhone3's app store listing because iPhone3's 480x320 screen can't fit such a size? Or does Apple downscale for me?

Screenshots are scaled down to fit the screen, but quality is not lost. It's basically like using image@2x.png.
