First Application with Push Notification in the App Store?

A member of iPod Touch Fans has reported that they have spotted that Tap Tap Revenge has been updated with support for Push Notifications. Users with the new version of Tap Tap Revenge and iPhone OS 3.0 will have badges on the Tap Tap Revenge icon showing the number of unread feed items and receive alerts when a friend challenges them to a game. This is probably the first app to get Push Notification publicly and it allows you to disable or enable it via the Settings app.
