Last month, India became the second country in the world after China to cross one billion mobile phone connections. This makes the little device we hold in our hands and place by our bedside every night the most used technology gadget in history. Consider the numbers: there are 160 million television sets in India. And just 120 million radios.
As prosperity seeps through the countryside, even more mobile phone growth is possible. In advanced economies like the United States, France, South Korea and Finland, there are more mobile phones than people. For example, South Korea with a population of 50 million has 56 million cell phones. Source
