How to handle hi and low resolution Icon.png applications for iPhone and iPhone4

Question

I have already provided both Icon.png (for iPhone) and [e-mail] (for iPhone4). The fact is that when I just provided Icon.png with a size of 144x144, the console will display this message:

"iPhone / iPod Touch: Icon.png: icon sizes (144 x 144) do not meet size requirements. Icon file must be 57x57 pixels in .png format (-19014)"

But it displays the icon well on iPhone and iPhone4.

I want to remove this problem, so I reduced the size for Icon.png to 57x57 and created [e-mail] with a size of 144x144. After that, the iPhone icon seems fine, but iPhone4 uses Icon.png and the icon displays a low resolution image.

Any suggestions? Thank!
