title: How to get main page from any part of Windows Phone 7 application?
body: <p>Is there any way of getting main page object from any of its child controls? As a possible solution I see here bubbling through parents and stopping as soon as a parent is of PhoneApplicationPage type. It is fine for me, but what if I need to do that from other pages?
  I.e. How to get main page of an application from everywhere within the application?</p>
