Africa's mobile economic revolution

The article here describes how the massive growth in mobile phone ownership is fuelling Africa's economic growth.

From the article:'Africa has experienced an incredible boom in mobile phone use over the past decade. In 1998, there were fewer than four million mobiles on the continent. Today, there are more than 500 million. In Uganda alone, 10 million people, or about 30% of the population, own a mobile phone, and that number is growing rapidly every year.'
