title: identify each iphone device in iOS SDK
body: <p>I need to determine each iOS device.</p>
  
  <p>In the past SDKS, there's a way to identify UUID by the command</p>
  
  <pre><code> [[UIDevice currentDevice] uniqueIdentifier];
  </code></pre>
  
  <p>But in iOS 5.0, this function is deprecated. Is there any way to do this similar task?</p>
  
  <p>Thank you!</p>
