I'm back from my wanderings with a very full show for you. First, we hear about the re-release of a mobile phone-based video game called Silverback. Then, to Zimbabwe to hear about FrontlineSMS. We'll have a studio talk with The World's Alex Gallafent about his multimedia-laced trip to the Amazon, and a chat with Cyrus Farivar about his trip to the Baltics. And somewhere in there, we'll talk about a new social networking site designed to bring donors and malaria researchers in Africa together. And yes, finally, a piece on Phorm.
