The iPhone now accounts for 50 percent of mobile Web traffic from smartphones in the U.S., according to an AdMob Mobile Metrics report released this morning. Over the past six months, the iPhone has taken share from Blackberry and Windows Mobile. In August 2008, the iPhone made up only 10 percent of mobile Web traffic from smartphones. During the same time, Blackberry’s share has gone from 32 percent to 21 percent (with the Curve and the Pearl coming in stronger than the Storm), while Windows Mobile has taken an even bigger hit, declining from 30 percent to 13 percent. Palm is also down to 7 percent from 19 percent six months ago.

The only other smartphone operating system that is showing gains in mobile Web usage is Android, which has captured a strong 5 percent share just three months after launch. And that is up from 3 percent in January. The gains shown by the iPhone and Android show what is possible when phones are built with fully capable browsers and support a rich array of Web apps.

On a worldwide basis, smartphones running on the Symbian OS (mostly from Nokia) still dominate mobile Web traffic with a 43 percent share. But that is down from 64 percent in August. The iPhone has gone from 4 percent to 33 percent of mobile Web traffic on a worldwide basis. All the other mobile operating systems are down as well.

This data is extrapolated from AdMob’s mobile ad network and only looks at smartphone share. Overall, smartphones generated 33 percent of worldwide mobile Web traffic, up from 26 percent six months ago. The full report is embedded below.
