HOWTO remove device tokens received by Apple APNS feedback
I am successfully fetching Apple APNS feedback data via PHP. The structure that I am getting (after some processing) looks something like this: timestamp device token My question is how to know which of the device tokens should I remove from my database and stop sending notifications to them.

The timestamp sent by Apple indicates the last time the push service attempted to deliver a message to the device and found the app to be uninstalled. If the device has re-registered with your service since then there is no need to delete it.
