Camera and preview in vertical view

I’m using Unity 4.5, instead of the horizontal camera, I would like to have it vertically (like screens on smartphone). So in the transform box of camera I entered 90 for the Z rotation.

The physics go in the right way, but the camera preview remain horizontally. How can I turn it of 90°?

Why don’t you just change your resolution at the top of the game view window?

You can set it to any size there.
