title: Change ListBox selected item on finger tap, not on finger release
body: <p>The Windows Phone <code>ListBox</code> control changes the selected item when the user releases the finger after having tapped the item. I would like the selected item to change as soon as the user taps the item, without waiting the finger to be released. Is there any way to achieve this?</p>
  
  <p>Actually what I want to do is to handle the ListBox "Hold" event to do something on the selected item. Currently, two taps are needed (one short tap for selecting the item, and another one for the hold behavior), and I would like one tap to be enough bor both changing the selected item, and the hold behavior.</p>
