Rovio Mobile's Angry Birds, still one of the most popular paid iPhone games, has an update available for iPhones. The update includes 15 new levels and a little spring cleaning on the welcome page. The update also includes Retina support for the iPhone 4 and integration with Apple's new Game Center.
What the update doesn't seem to include though, is the eagle that Rovio was talking about at Nokia World. With a few levels still needing completion, this news editor cannot wait for the next update.
