According to Robyn Jeffrey, the mobile phone changed humanity's way of life more than any invention since shoes, and the power of the mobile phone is "not in the mobility, it is the autonomy," he says. In 2001, India had 4 million cell phone subscribers, or 35 mobiles for every thousand people. Ten years later, that number had exploded to more than 750 million and 658 mobiles per thousand people. Over just a decade, the mobile phone was transformed from a rare and unwieldy instrument to a palm-sized, affordable staple, taken for granted by poor fishermen in Kerala and affluent entrepreneurs in Mumbai alike.
