Forgive me if I am mistaken, but don't all you need is a UDID to send a push message to a device? I.E. via Urban Airship.

No, you need a push token, which is a combination of device id and app id, and is only generated when the user authorizes the app for remote notifications. Additionally, you need a certificate on the server that is authorized to send messages to that app id.

The push token is static for the device installation: it is not in combination with the "app id".

Yeah, but the certificate used to push is.

Effectively, it's the same result: you can only push to one app with one set of credentials, and credentials are not shared between apps.

Good to know, thanks for the explanation.
