Constraining Viewport size in Unity to IOS Size and GUI texture placement

Is there a way of making the unity viewport constrained to the size of the Target platform? I am hacking the placement of GUI textures now by guessing.

There has to be a better way of seeing where things are going to line up without building and looking where your gui textures are going to end up - right?

do you talk about the editor view or game view?
The game view allows it out of the box, the dropdown menu at the top left offers you the options for the current platform of the project

omg… beautiful! thanks Champ!
