title: Does the iphone mail app inform safari of send/cancel choice of user?
body: <p>Let's say I have a mailto link on an html5 mobile app viewed in iOS safari, like mailto:whatever@whatever.com. Clicking the link opens the iphone mail app modal composer. I want to thank the user for sending an email, so my web app needs to know if the user clicked send or clicked cancel.</p>
  
  <p>After clicking "send" or "cancel" the modal closes. Does it report the send/cancel decision back to the browser? Does it report anything at all, or just return the user to the current state of the requesting web page?</p>
