Unsuscribe to WP7 notification for uninstalled application

Question

I have a toast notification system that is working on WP7. When I send a notification, all registered devices receive the toast notification.

But, If someone uninstall the application, I will continue to try to send to the registered device (in fact, I will ask Microsoft service to send to the unavailable device). Is it possible to detect if someone uninstall the app, then I can remove it from my list of device to send. Or maybe can Ms services tell me if the app as unsuscribe to the toast notification ?

My list of registered device grows infinitely ....

Thanks in advance for any Help, Best regards

You can't detect if the user deleted the app, but can always check the subscription status return code when you send a notification!

Check here for the return codes, specifically where the SubscriptionStatus != Active
