Targeted for iPad option in Xcode
In Xcode when creating a subclass of UIViewController, an checkbox named "Targeted for iPad" exists among others.  
What if I want to create an app that runs on iPhone and iPad (I think it is called universal application)? should I check it?  
If I checked it, what is happening under the hood?
