It would be a different thing entirely if ordinary people from the continent of Africa got $307 apiece, but of course it doesn't work like that. $307B to African governments, typically dictators (Hosni Mubarak is probably included in that figure), who take their cut, and then use a lot of the remainder to buy F-16's as per their agreement.
I wonder what fraction of this money will actually go toward internet infrastructure. You know that half of the dictators involved here will proceed to make their cousin the new minister of internet development, and his company will be tasked with the herculean task of installing the new infrastructure all by themselves.
I used to be a liberal. Then I learned about incentives. Suddenly the gap between promises and results for government projects made so much more sense.
