First 'Push' App On The App Store, iPhone 3.0 Appears on Apple's Servers

Tapulous' Tap Tap Revenge 2 [App Store] seems to be the first application (to our knowledge) to be posted to the App Store with support for push notifications. The new feature only works under the iPhone 3.0 software and allows players to invite their friends to a game.

Additionally, MacRumors reports that Apple has posted the iPhone 3.0 software to its servers for the iPhone 3G S. It's unlikely that the software will work on anything but the 3G S, and may not even load on a 3G. We recommend against trying this on anything but an iPhone 3G S.
