How to implement Push notification in iPhone?

The Apple documentation on Push Notifications is very clear, with sample code:

If you aren't interested in implementing your own server solution for providing push notifications to your client, you might be interested in these solutions:

Each charge a fee for push notifications sent, but they also abstract away most of the initial setup complexity and, obviously, the costs associated with maintaining one's own server/bandwidth.

If you're interested in hosting your own solution, I've had success with Apns4r, a Rails plugin: http://github.com/searls/Apns4r

There is also an open source python Apple Push Notification server, in case you want to roll your own and don't fancy any of the options that Justin mentioned.
