Lamenting the time you restored your iPhone and lost that beloved VLC app because it's no longer available on the App Store? Cheer up, there's an iCloud for that. The service allows you to re-download any app you've previously purchased on any of your iOS devices -- including killed apps. We decided to give it a whirl, testing our luck with an iPhone 3GS humming along on iOS 4.3.3. Upon browsing the Purchases section of the App Store, we beheld Tris, an app that hasn't been available in nearly three years. Sure enough, we pressed the iCloud icon and within seconds, the ol' Tetris clone was back in action. So if you were one of the four people that downloaded I am Rich before it was killed, you'll be sure to enjoy that $1,000 investment for years to come.

[Thanks, Chris]
