Solution
No, there is no cost. The only "gotchas" are that your app has to be in the app store(i.e. no jailbroken apps), and you have to maintain a server for pushing the events.
Problem
Is there any cost for using the Push Notification Service? I know it requires using my own server to send notifications, but the signals are passed through an Apple server. There are no server transfer fees?
