title: How do I authenticate for Twitter friends_timeline?
body: <p>This is my first web API project, so I hope the solution to this isn't blindingly obvious. </p>
  
  <pre><code>// Contstruct the http request
  NSString *urlString = [NSString stringWithFormat:@"http://%@:%@@twitter.com/statuses/user_timeline/%@.xml?count=5", username, password, friend];
  NSURL *url = [NSURL URLWithString:urlString];
  NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
  
  // Recive the data from the synchronous request
  NSData *urlData;
  urlData = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:nil error:nil];
  </code></pre>
  
  <p>The results returned from this query look fine <em>except</em> they don't reflect if I've favorited them or not. All tweets return "false", even if the authenticating user has starred them. I'm fairly confident that I'm authenticating correctly as code further down that does require authentication behaves correctly. </p>
