title: When phone is offline GCM stores a LIST of messages or only the last one, just like APNS?
body: <p>When phone is offline GCM stores a LIST of messages or only the last one, just like APNS?</p>
  
  <p>I've read a lot about it, but as the documentation says:<br/>
  1. The GCM connection server enqueues and stores the message if the device is offline.<br/>
  2. When the device is online, the GCM connection server <strong>sends the message to the device.</strong></p>
  
  <p>this part 'sends the message to the device' is confusing me. Does it deliver the <strong>list</strong> of messages?</p>
