Urban Airship powers Push Notifications, In-App Purchase, and Subscriptions for mobile applications across major mobile platforms.

Ever wondered how to implement push notifications or badges for you iPhone app? I have. I planned to learn it as a friday project at work, but as I started to read about it I realized Apple did not want to make it such an easy trip for me. Then I read about Urban Airship and a couple of hours later it was implemented and ready in my app. Head over to the documentation to see how.
