Multiple items change between publisher push message.
The Cloud to Device PuSH message service only allows me to push 1024 bytes to the phone.
This simplest solution to this means that I only push the first story in any content update. Originally this was not an issue as Superfeedr pushed us 1 message per item. Now Superfeedr is batching messages together (which is perfectly legal).
Push message sent to the phone will contain a callback, that will allow the phone to pick up extra messages that will not fit in the C2DM push message
