Apple's iPhone and iPod touch dominate most of the world in the mobile Web browsing battle, with a 40 percent global total that bests its rivals, according to a new study.

A report released by AdMob on Wednesday, the iPhone OS market share has grown by 7 percent in the last six months, while Nokia's global share has dipped from 43 percent to 34 percent.

Meanwhile, Research in Motion carries 8 percent in the August report, Android with 7 percent, and Windows Mobile with 4 percent.

The iPhone is the dominant platform, except in Asia and Africa where Nokia's Symbian OS carries the lion's share. However, in the U.S., the iPhone and iPod touch have 52 percent share of the mobile Web market, with both devices the top handsets.

Within the smartphone sector, Apple is also on top, followed by the HTC Dream and Palm Pre at two and three, respectively.

AdMob's Report is based on Web and application use from the advertising company's 9,000 publishers and 3,000 applications worldwide.
