title: Opening Native App. from Safari
body: <p>I know iPhone apps. operate like sandboxes. Meaning that they don't have access to other apps' files. And I have also managed to open a website in Safari from a Native App() using:</p>
  
  <pre><code> openURL:[NSURL URLWithString: Website_Address] 
  </code></pre>
  
  <p>There are four Native apps that I have seen being opened from safari.</p>
  
  <ol>
  <li>App Store app</li>
  <li>Maps app</li>
  <li>Email app</li>
  <li>Phone app</li>
  </ol>
  
  <p>Is there a method of opening my own app from an iphone website in Safari(maybe some html/xml/php etc code)?</p>
