A friend of mine switched from iphone 4s(after saying its the best phone ever) and turned to S3 and he says he is not looking back. When I asked why you love the S3 one of the things he said was that "Everything that you pay for on iOS is free on here" I said "You might be pirating" , he said "No I am using Google Play" I didn't test this but the other day friends said Bad Piggies was out, so through a friend's phone we downloaded the game and there were SD and HD versions. Both games were FREE. I just checked the iTunes store and both games are for $0.99 and $2.99 . How is this possible? If developers are really doing this, how can they make money? If they do it by using ads, well iOS has ads too I see no one using it to make free apps? Can any one explain?
