title: iPhone address book external change call back
body: <p>I'm developing app with using of native address book. I've registered a callback to receive a notification when address book has changed externally.</p>
  
  <pre><code>ABAddressBookRegisterExternalChangeCallback(myAddrrbook, changefunction, self)
  </code></pre>
  
  <p>My app can make new records inside <code>AddressBook</code>, to do it I'm using <code>ABNewPersonViewController</code> like that:</p>
  
  <pre><code>ABNewPersonViewController *controller = [[ABNewPersonViewController alloc] init];
  
  controller.addressBook = myAddrrbook;
  </code></pre>
  
  <p>The problem is, that I still receiving notifications when I using my own app like it changed somewhere else. 
  But when I run on the simulator, everything is <code>OK</code> and no notification sent when I adding a contact.
  How to avoid receiving notification on device?</p>
  
  <p>Does anybody had face such problem?</p>
