title: iOS Universal App question
body: <p>I have submitted my iPad app to apple and got approved. Now, i want to add iPhone support to the App.</p>
  
  <p>My question no.1 is: </p>
  
  <p>Q1. is it possible to make the app universal at this moment after submission? </p>
  
  <p>If yes, i have question no.2</p>
  
  <p>Q2. my iPhone app is exactly the same as the the iPad but only a few views are in different look due to the customization in screen size. What should I do in XCode to specify which class that iPhone/iPad is using respectively? I can build them smoothly when i separated them into 2 projects.</p>
  
  <p>Thank you.</p>
