title: Push Notifications without Azure service?
body: <p>We tried hard to manage using <em>background services</em> in WP8, but even with <code>Location Tracking</code> it has lot many limitations. So we chose to go for <code>Push Notifications</code> to work as <em>background service</em>. </p>
  
  <p>I have gone through lots of resources talking about Push Notifications with <code>Windows Azure Mobile Service</code>, is there any way we can use Push Notifications using our own server?</p>
  
  <p>Secondly, what is exactly <code>MPNS</code> (Microsoft Push Notification Service)? Is it some service running in my mobile? Is it free or paid? Where I can find all these information. </p>
  
  <p>Regards</p>
