title: Universal application with IOS 4.2 and Xcode 3.2
body: <p>I'm developping Iphone application and I want to convert it to a universal one. 
  I found many tutorial that deals with this issue but they seems to be ancohérent to the new release of SDK and Xcode.
  As many said I think that making a universal application is so easy.
  Can you give me the necessery steps or a tutorial link? Thanks.</p>
