title: iPhone: Is it possible to go back to the previous application after handling custom URL?
body: <p>I know that iPhone applications can be launched via a custom URL such as myapp://something. But is there a way to go back to the previous application after handling the custom URL?</p>
  
  <p>For example, I have the following scenario.</p>
  
  <ol>
  <li>Follow a link from iPhone Twitter application.</li>
  <li>Twitter shows a link that redirects to a custom URL.</li>
  <li>My application is invoked and handles the URL.</li>
  <li>After completing the job, I go back to the Twitter app.</li>
  </ol>
  
  <p>I want my application to handle a custom URL like a modal dialog box. Is it possible?</p>
