Based on the latest stats from M:Metrics, the iPhone is delivering on its hype, radically changing what people are doing with the mobile Web.

Check out some of these figures:

• The iPhone is already the most popular device for accessing news and information on the mobile Web, with 85 percent of iPhone users accessing news and information in the month of January.
• 30.9 percent of iPhone owners watched mobile TV or video, versus a 4.6 market average, and more than double the rate for all smartphone users.
• 30.4 percent of iPhone owners accessed YouTube, compared to 1 percent of all mobile phone users.
• 36 percent used Google Maps, compared to 2.6 percent of all mobile users.
• Usage of social networking is also popular among iPhone users: 49.7 percent accessed a social networking site in January, nearly twelve times the market average.
• Twenty percent of iPhone owners accessed Facebook, one of the first Web properties to customize its content for the iPhone, versus 1.5 percent of the total mobile market.

The iPhone offers a taste of the future; iPhone users are using the devices in all sorts of leading edge ways. It also shows how mobile users will use Internet media when they get capable devices and unlimited data plans.
“The iPhone has certainly delivered on its hype,” said Mark Donovan, senior analyst, M:Metrics. “Beyond a doubt, this device is compelling consumers to interact with the mobile Web, delivering off-the-charts usage from everything to text messaging to mobile video.”

“While the demographics of iPhone users are very similar to all smartphone owners, the iPhone is outpacing other smartphones in driving mobile content consumption by a significant margin,” said Donovan. “In addition to the attributes of the device itself, another important factor to consider is the fact that all iPhones on AT&T are attached to an unlimited data plan. Our data shows that once the fear of surprise data charges is eliminated, mobile content consumption increases dramatically, regardless of device.”
