title: when should i build app with armv7s support?
body: <p>Today when i try to submit my app (update) to appstore, the Organizer told me :</p>
  
  <p>"iPhone/iPod Touch : application executable contains unsupported architecture(s): armv7s"</p>
  
  <p>I clearly remember that its last version was submitted with both armv7 and armv7s set and succeeded, but now Organizer changed its mind?</p>
  
  <p>to remove armv7s flag is simple, but my app is Universal, will the armv7s-removed app run on all iOS devices (iPhone 5 for example)? when should i build with aremv7s?</p>
  
  <p>Thank you.</p>
  
  <p>EDIT : xcode version here is first 4.5 then i tried 4.5.1</p>
