I'm reading blogs from the financial conference call. So far Apple has been selling the the 3GS in 18 countries where as the 3G is available on 80 countries. And when the 3G launched, it was available on more countries as well. And still, Apple managed to sell over 5.2 million iPhones while supplies are tight.
Oh, and 130% increase in iPod Touches sold compared to a year ago. This number will go up next quarter and next year.
