title: What's the difference between "Deployment target" and "iOS deployment target" in Xcode 4
body: <p>I've been living in doubts since Xcode 4 release about <code>deployment target</code> option.
  There are two options to set.</p>
  
  <ol>
  <li>First is on "TARGETS" pane and is called <code>Deployment Target</code>. This one serves the purpose to set the lowest possible iOS version that app can run on.</li>
  <li>Second is on "PROJECT" pane and is called <code>iOS Deployment Target</code>. Well, this is the one that I'm not familiar with.</li>
  </ol>
  
  <p>Can someone please explain it to me how to properly set second option if I support let say iOS 4+ ?</p>
