According to chief operating officer Tim Cook, very simply, this should mean that countries such as South Africa will receive the much awaited Apple iPhone 3G on this date, the 22th of August. According to MacWorld:

Questions from analysts about the tight supplies of iPhone 3Gs prompted Cook to mention Apple’s expansion plans. Cook pointed out that the shortages are a result of “overwhelming demand” and that Apple was confident enough in its ability to boost production that it would expand the iPhone’s market by 20 countries on August 22.

The countries that haven’t received the Apple iPhone 3G are listed on the image above. I’ve seen some heavy pre-sales marketing on the South African side, and I don’t doubt the same is happening in other parts of the world. Now Apple just has to fulfill their promise.

Besides these 20 countries, Apple pretends to introduce the iPhone in more than 70 countries by the year’s end, but low stock isn’t helping their delivery. Of these 72 countries already listed, 22 have received it, 20 should receive it on August, and the rest aren’t accounted for yet.
