Finnish firm Rovio is celebrating the third birthday of Angry Birds by releasing a hefty great update for the little game that started it all.

The original Angry Birds on iOS has received 30 new levels. That's 15 fresh Bad Piggies-themed stages and 15 more Birdday Party-themed levels.

There's also the addition of Pink Bird. This bubbly chick can levitate blocks and pigs, and then drop them from a great height. Handy.

The game also gets full iPhone 5 support, which means all the Angry Birds games - bar Angry Birds Rio - are now compatible with the 4-inch widescreen on Apple's new blower.

By the way, we celebrated Angry Birds's third birdday (sorry) yesterday by publishing a complete rundown of this feather-flapping franchise. Enjoy.
