I read about this ingenious project called the Question Box in the Indian Express this Sunday. It is a great example how simple technology can help people around the world (especially the 3rd World).
It relies on a simple cell phone put inside a durable metal box and provided with two buttons - green and red. When you want to ask a question just press the green button and the cellphone connects you to one of volunteers, he or she then looks up the question on the internet or a database to answer the query.
I think this device is a great way of putting information in the common mans reach, where most people in rural India/Africa can't even read and write, let alone use a computer.
The people at OpenMind have even developed an open source software which can used to start your own Question-Box project.
