Angry Birds sells 6.5M units on iPhone and flies to new smartphones

The creators of smash hit game Angry Birds visited me yesterday, and they were all smiles. The two developers from Helsinki-based company Rovio have sold more than 6.5 million copies of the iPhone game on the App Store since December. And the free version of the game, which entices people to upgrade to the pay version, has been downloaded more than 11 million times in 60 countries.
