"It's time to step back in time by four years and revisit your old feathered friends. The original, full Angry Birds has 15 new levels, and it's free for iOS.\nIn an effort to jump start new downloads/users, Rovio took down the paywall for the full versions of Angry Birds on iOS devices and added the new levels. While it's one of the world's most popular mobile games, Angry Birds recently dropped off the top 80 highest-grossing apps for the first time in nearly three years.\nAs Appsfire first reported, the app's price dropped from $0.99 (iPhone) and $2.99 (iPad HD version). The previous free versions of both games, which only offered a few playable levels, have been removed from the store completely. \nHowever, the full Angry Birds games are now considered freemium, requiring in-app purchases for features such as unlimited use of Mighty Eagle or Birdquakes, which shake the piggies houses down on top of them. Mighty Eagle is best used when you're stuck, as the bird swoops in and smashes the piggies for you.\nIt's not clear as to whether this will be a permanent change, or if it will all change back once Rovio boosts its user base. \nImage courtesy of Rovio"^^<http://www.w3.org/2001/XMLSchema#string>
