Mimicing the iPhone screen in osx

I’ve just started to work with Unity and I’m intending to make casual games for the iPhone/iPod Touch.

Is there a way to set a fixed size for the player window in osx (and the game view in the editor) so it will look exactly like the iPhone (320x480 px)?

It would help a lot when I need pixel-perfect alignment.

I am intending to build a 2D game, so I want my camera to use orthographic projection and have the size 320x480 units, so I get a nice 1:1 unit-to-pixel ratio.

Thanx a lot or any advice!

if you’re using unity iphone, just select “iPhone Tall” or “iPhone Wide” from the aspect ratio dropdown on top of the game view!
