That quoted article talks about what phones to use when they're sent for field works in 3rd world countries, not about those living in the 3rd world countries themselves.

Android is getting huge in 3rd world countries. They're showing up in local brands (OEM-ed from china, obviously) at sub $100-150 price points.

Moreover, I should point out that most chinese knockoff phones make use of Nokia's battery and charging adapter specs. So you will find:

1. Many knock off Nokia batteries and adapters in such marketplace
2. They're not only intended for Nokia branded phones

Rhetorics (sometimes) makes interesting read, but they don't make facts out of fiction.
