where did those numbers come from?
from outside the USA iphones are usually reported as NOT having the market dominance.
I gave the citation: IDC report on worldwide smartphone Q12012 sales dated May 24, 2012, about as up-to-date and as accurate as you can get. As for the carrier figures in the US, those came from AT&T and Verizon 1Q 2012 q10 financial reports and were reported in the press. You can add that the iPhone is the best selling smartphone in Japan.
