Social media commentary: How have mobile phones changed Africa?

Using the hashtag #cnnmobilesociety, we asked Facebook and Twitter users how mobile phones have changed lives in Africa. The Kenyan money service M-Pesa was a popular response. The M stands for mobile while Pesa means money in Swahili. The service enables users to transfer money quickly using text messaging.
