With an About screen you probably just want to show a view and then dismiss it. So rather than use a whole new view controller you can just cover the current view.

Assuming you have an ivar

UIView *aboutUsView;

with the appropriate property.

In your view controller do:

[[NSBundle mainBundle] loadNibNamed:@"AboutUsView" owner:self options:nil]; // Retains top level items
[self.view addSubview:aboutUsView];  // Retains the view
[aboutUsView release];

To remove the view, say in an action connected to a button on the view, do:

[aboutUsView removeFromSuperview], aboutUsView = nil;  // Releases the view
