Users of the Apple iPhone can't seem to get enough of the mobile Internet. According to AdMob, the Apple iPhone was the fastest growing device in the world last month and ended August with more than 2.9 million mobile Web page requests per day. Other devices are making headway, too. Seems this thing called the "mobile Internet" just might take off.This statistic isn't a total surprise. I use my iPhone more as a data device than as an actual phone. I am sure many others do the same thing. Engadget recently reported that 96% of all the mobile traffic to its Web site comes from the iPhone. That's astonishing. The top five smartphones in the US -- the BlackBerry Pearl, Palm Centro, BlackBerry Curve, Apple iPhone, and Samsung Instinct -- generated 12.9% of all U.S. traffic in August, a 2.4% increase over July. Smartphones from Nokia and RIM had strong showings. AdMob reports that Nokia has 62.4% of worldwide smartphone traffic in August, with more than 50 percent in every region except North America. RIM is in second place worldwide with 10.8% of smartphone traffic with the large majority of that coming from North America. RIM leads in the U.S. with 31.2% of smartphone traffic and manufactures three of the top 10 devices. As more and more phones ship with full HTML browsers, usage of the mobile Internet will only continue to swell.
