title: iPhone & iPad - is it OK to change the product name on Xcode?
body: <p>I am preparing a update for one of my apps.</p>
  
  <p>I want to change the "product name" of this application in Xcode.</p>
  
  <p>Will this give me any problems? I mean, will users that already have bought the application be able to download the update?</p>
  
  <p>What exactly identifies the application for iTunes and the iPhone? The bundle identifier and version on info.plist?</p>
  
  <p>thanks for any help.</p>
