title: An App ID with Identifier is not available. Please enter a different string
body: <p>I've just enrolled in the Apple dev program, but when trying to create an APP ID in the Member center, I receive this message:</p>
  
  <blockquote>
    <p>An App ID with Identifier is not available. Please enter a different
    string.</p>
  </blockquote>
  
  <p>Before enrolling, I was using the same account (but not part of the developer program), and building my app for my own phone.</p>
  
  <p>I'm 200% sure this bundle ID is not taken by anyone else but me.</p>
  
  <p>How is that possible in such case? Can XCode register an APP ID by itself ?
  I also notice an app id called "XC Wildcard" which is defined for any id "*"</p>
  
  <p>I'm really kind of lost, so any help would be really apreciated.
  Thanks!</p>
