Mark your calendars for August 22, when many countries will start offering the iPhone 3G for sale. Here's a list of the countries that are expecting launches that Friday (and their associated carriers, in parentheses):

Apple said last month that 20 countries would be getting iPhone 3G on the 22nd. Singapore is also rumored to be releasing the iPhone 3G that day, but SingTel hasn't confirmed their participation yet.

In other news, Virgin Mobile is now offering iPhone 3G service in Australia. This addition gives the country four providers to choose from: Vodafone, Optus, and Telstra are the other three. Sadly -- according to this article, they're already out of stock.
