The Push Notification Service Programming Guide is here: http://developer.apple.com/iphone/library/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Introduction/Introduction.html Be advised, though, that push notifications are really directed at the *user*. Yes, the alerts you can push provide a convenient way for the user to start up your app (and your app is specifically informed of that), but this isn't like waking up a daemon process on the device. Your app can still only run in the foreground, and only at the discretion of the user, and will still be quit when the user is done with it. (Users can also turn off the push alerts entirely.)
