> By 2012, there will be 2.3 billion mobile devices in use, the equivalent of 70% of the world’s population. Given that the world population is estimated to hit 7 billion next spring, I think this number is a bit absurdly off. 70% of 7 billion is 4.9 billion. I think google should use google next time they need to find out the world population, because they're estimating it at 3.3 billion.
