Angry birds is a very entertaining game for touch mobile phone and in tablet PCs
I saw angry birds for so many times in the OVI store but i didn't download it. I never heard it before from the people who has iphone or touch phone. i never see anyone playing it before on their phone.
Since its free then my curiosity take me to download it. I tried and really I enjoy it. While playing it you'll learn the techniqes etc.you'll aim for higher score.
The good thing is they are giving an update, it means angry birds is like a never ending game that when you finished all and you get the highest score then they will update and there is new themes of the game.
