There is a problem of screen resolution in Flex Mobile Development

the iphone4:normal

the ipad :normal

but iTouch 4:

it does not see normal ,i dont know why this?

i can confirm that when screen resolution(width/height) small  just like iTouch(320*460) it's difference

i  use applicationDPI="160" applicationDPI="240" applicationDPI="320" but it does not work.,how can i do that?

Thanks Very Much~
