Or another use-case of detecting uninstalled applications would be to support failover to another messaging channel such as email or SMS. What application experience are you trying to improve after the user has deleted an application?

Is there action you want to take on uninstall, or is this information that you want to use in aggregate and not specific to a particular user?

System send notifications to User1. Other users can see that User1 was sent a notification. User1 uninstalls application. NOTE: we have no indication of state change on our server side when the user uninstalls. They still show up in our system with a device ID and "on call".

Today - we check the APNS feedback service every night. We receive notification from the feedback service that User1's device ID is invalid. We find the user in our system by device ID, and automatically mark them "off call" and clear out their device ID in our system so that we no longer attempt to send push notifications to this invalid device. Now that we have the message taken care of, all we need to do next is send out the message.

Each message comes back with a set of data that allows us to understand what happened with our push notification as well as throwing exceptions in the cases of server failures. APNS has a feedback service that you must listen to. Apple states that they monitor providers to ensure that they are listening to this service. The feedback service simply returns an array of Feedback responses. Compression is used to increase notification throughput and reduce the need to open simultaneous connections.

Developers who have built their own notification systems can make the switch entirely on their servers since no app-level changes are required. Update: Apple has now made an official announcement here APNs first debuted as a way to send notifications to devices in iOS 3, and has remained largely unchanged since then.

APNs has always been a difficult implement and use API for many reasons, including: Notifications must be serialized to a binary format and sent individually over a secure TCP socket.
