An interesting article here on the growth of Social Networking in South Africa. While this article is focused on Facebook and Instagram, the section that interested me was this:

Blackberry and Nokia are still the most popular brands in South Africa, accounting for around 87 percent of the smartphones in the country. Blackberry holds the majority of that with around 46 percent of South African using a Blackberry. Nokia's share of the local market is around 41 percent.

iPhone is way in last place with 3%. It's often forgotten that the entire global market isn't just the iPhone, and nor is it Facebook and Twitter. Viafo's strength is to free developers, brands, carriers and agencies from having to focus on 2 platforms and only 2 social networks.
