The iPhone has room to grow

Apple's most popular product is not for sale to half the world's 6 billion mobile users

FORTUNE -- The next time someone tells you that the market for Apple's (AAPL) iPhone is saturated, think of the chart at right posted Wednesday by Asymco's Horace Dediu.
At last count, he writes, the iPhone was being sold by only 30% of the world's 816 mobile phone operators. Some of those carriers are bigger than others, of course. But all told he estimates that the iPhone is available for direct sale to only about 50% of the world's 6 billion mobile subscribers.
Google's (GOOG) Android, by contrast, is available to nearly 100% of those subscribers.
Where does the iPhone have the most room to grow? According to Dediu, the top 5 countries with unaddressed subscribers are

1. India: 658 million
2. China: 622 million
3. Pakistan: 116 million
4. Russia: 102 million
5. Nigeria: 89 million

But the iPhone also has room to grow in the developed world. Dediu estimates that Japan is a 69-million-subscriber opportunity. Even the U.S. has 80 million subscribers without direct (i.e. subsidized) access to the iPhone.
