Rovio has made one its classic mobile games available on the iPhone, iPad and iPod touch available for free by slashing the prices of Angry Birds and Angry Birds HD to nothing for iOS users in both the United States and United Kingdom. It is unclear if this is a permanent move or just a limited-time offer, however Rovio also removed the free demo versions of the apps, which were limited to only a few levels.
