title: Can I open phone app using URL scheme in iPhone?
body: <p>Can I open the phone app on iPhone using URL scheme? if yes then how?
  I know I can dial a number using this:</p>
  
  <pre><code>[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://8004664411"]];
  </code></pre>
  
  <p>But I don't want to dial a number, I just want to open the phone as I click on the phone icon on home page.</p>
