title: What is the user agent string for iOS / MacOS iMessage?
body: <p>I'm parsing s3 logs to identify requests made from iMessage previews (on Mac OS Sierra &amp; iOS 10).</p>
  
  <p>There are few common types of UA strings, but I can't tell which are from the browser vs. imessage. I'm hoping it's a unique UA from Safari:</p>
  
  <ol>
  <li>`AppleCoreMedia/1.0.0.14B100 (iPhone; U; CPU OS 10_1_1 like Mac OS X; en_us)</li>
  </ol>
  
  <p>^ Gotta be iOS Safari, right?</p>
  
  <p>2.MobileSMS/1.0 CFNetwork/808.1.4 Darwin/16.1.0`</p>
  
  <p>^ I <em>think</em> MobileSMS means imessage (hopefully)</p>
  
  <ol start="3">
  <li><code>Mozilla/5.0 (iPhone; CPU iPhone OS 10_1_1 like Mac OS X) AppleWebKit/602.1.32 (KHTML, like Gecko) Mobile/14B100 Twitter for iPhone</code></li>
  </ol>
  
  <p>^ Twitter via webkit webview?</p>
