Sales of Smartphones have long been publicly ranked in Japan, listed at this site. From the start, however, they have, for whatever reason, put the iPhone at a disadvantage: they broke iPhone sales up by the amount of memory–e.g., the 16GB and 32GB versions have been listed separately. Artificially dividing it into two separate product listings has the effect of taking the iPhone down from 1st place more readily, and making it look like it is not selling as well. This helped the Galaxy S, for example, take “first place” in the rankings when the iPhone was still outselling it.

This is not done with other phones. The Galaxy S II, for example, comes in 16 GB and 32 GB models, but is listed as a single phone in the rankings.

Now that the iPhone 4S has come out, they have raised the bar for the iPhone even further: not only are they dividing rankings by capacity (three different models this time, 16, 32, and 64 GB), but they have added a new division: which carrier sells the iPhone. They list the Softbank iPhone 64 GB model separately from the Au iPhone 64 GB model. Since the iPhone 4 (two capacities) is still being sold, that means that iPhone sales are now broken up into eight separate listings.

Again, this is not done with other phones–the Aquos Phone, for example, is sold by multiple carriers, but is not broken up in this way.

Even with this marked disadvantage, the iPhone currently holds eight of the top eleven spots on the list, the 4S occupying all top six spots. In other words, the least popular version of the 4S (the 16GB version from Au) outsells all varieties of any other phone combined.
