It’ss on the market for only six months, and already the iPhone (with its Wi-Fi-only variant, the iPod Touch) is the most widely used browser for mobile Internet access in the U.S., Irish researchers StatCounter. At No. 2 is the Symbian OS in Nokia devices. Worldwide, the two positions are reversed. In any case, Windows Mobile – in all its versions – is just a blip.

As in March, the iPhone and iPod touch-account 0.23 percent of U.S. Web traffic, while business-friendly Symbian-based Nokia devices come in second place, although no StatCounter percentage of their traffic. Worldwide, Nokia comes in tops at 0.25 percent and the iPhone and iPod touch second at 0.08 per cent, despite its availability in a few countries.

Another researcher, NET applications, the iPhone / iPod touch in top position with 0.19 percent of global Web traffic, compared to 0.06 percent for all Windows Mobile devices. (NET applications is not the Nokia platform traffic.) In the search in the browser traffic, NET applications rolls the iPhone Safari and the desktop version, not as separate applications. Microsoft Pocket Internet Explorer browser claimed 0.03 percent, the Palm Treo Blazer browser to 0.02 percent, and the multiple-device grabs Opera Mini 0.04 percent.

iPhone key to success is the fact that it provides a uniform, full browser experience, said Neil McDonald, a Gartner analyst. By comparison, Windows Mobile platform is a broken, with separate PDA and Smartphone versions, as well as a version of the browser that doesnot full support of HTML.
