title: How to open preferences/settings with iOS 5.1?
body: <p>Looks like iOS 5.1 has broken the standard URL encoding for navigating a user to a Preference.</p>
  
  <p>For example:</p>
  
  <pre><code>[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=TWITTER"]];
  </code></pre>
  
  <p>Works in iOS 5.0 but not in iOS 5.1 (both device and simulator).</p>
  
  <p>Has anyone found a way to replicate this functionality in iOS 5.1?</p>
