Messaging (IM and email): For the three months ended in December, Yahoo was the dominate leader in with nearly 11 million U.S. subscribers accessing their accounts from a phone; Hotmail/Windows Live claimed 5.5 million subscribers. Together the two would easily outrank the 5.4 million subscribers using Google’s Gmail.

Browser (Search, News/Info and Weather): For the three months ended in December, the clear leader was Google with 7.7 million U.S. subscribers using their services from a phone. Yahoo came in second with 4.4 million subscribers, and MSN/Live only had 1.2 million. Yahoo and MSN/Live together still would fall behind Google’s search dominance, which grew an amazing 62 percent year-over-year.
