In the early 1990s, Iqbal Quadir, a Bangladesh-born MIT professor and entrepreneur, had the idea that cellphones could be used to help the very poorest people. Ten years later, with hundreds of "village phones ladies" in operation, did Iqubal's model for lifting developing nations out of poverty pay off? CBC News Sunday's Natasha Sweeney has the story of how one man, starting with one phone, helped a whole country leapfrog into the 21st century.
