This week, Africa Calling podcast brings you a number of feature reports from our correspondents on the African continent. From Cameroon, we'll take a look at the trend to return to natural hair in Douala. In Somalia, our correspondent looks at the business of taking back the country's aircraft registration. And in Sudan, we'll find out how people feel about the changes made (or not) in the country since the fall of repressive strongman Omar al-Bashir, two years ago this month.
