Set iPhone 4 resolution in game screen?

In Unity’s Game Screen I can set the display resolution to iPhone Wide or iPad Landscape. Does anyone know how to set the game Screen’s resolution to that of the iPhone 4 of 960x640 pixels?

iphone 4 support comes with Unity iPhone 3

Unity iPhone 1.x is iphone 3gs earlier and ipad only, not support for iphone 4
