I was in Rwanda last summer teaching a class on programming/entrepreneurship centered on mobile devices. The ubiquity and penetration of Nokia phones there is pretty incredible. Even some of the poorest of people have cell phones. Essentially, they are the only form of computing device for many of them, so it IS their smartphone. There are many services and businesses centered around SMS applications that are very useful. Rather than expensive plans, there are people lining the streets selling prepaid "airtime". Their 3G network is also just as fast as any I've had in the US despite not being connected to SEACOM (although this may be due to lack of traffic on the 3G network, I had a Nexus One Google provided while I was there). Nokia was one of the sponsors of my program because they see how valuable the African market is with their explosion of cell phone growth in the past few years.
