If there are shadows or fades in my wallpaper, the iphone butchers them. You can see the little pixels. It makes an image with shadows or fades, look grainy. Does anyone know what i'm talking about? Is there any solution to this problem? Don't say return it. Please your insight. It's not as easy to notice when the screen is dimly lit. When it's on full bright, it's more so obvious. It's driving me nuts. I want images to look nice and sharp. Is there a better way to render an image to look optimal on an iphone.

For example, I put the default "tiger" (mac ox) wallpaper on my iphone. With something that detailed, I can see the little pixel dots in the darker and lighter areas.
