title: problem in displaying a xib as Ipad in universal application
body: <p>I have an already running iphone app with target OS 3.1. I am trying to transform it into a universal app.
  I am not going to change the model, only the xib.
  So I wrote the ipad xib in IB, then I went to info.plist and add MainIpad Nib for ipad pointing to a proper MainIpad.xib.
  I also set Target Device Family in project info to ipad/iphone.</p>
  
  <p>That seems to be not enough, whenever I run ipad simulator, I always get the MainIpad.xib view resized as iphone, actually it's just showing an iphone inside an ipad. I also tried to set the CGRect manually to the ipad size. The result is a bigger view still clipped into an iphone.</p>
  
  <p>Can you point out what I am doing wrong and suggest the proper way to convert in universal app ?</p>
  
  <p>thanks</p>
