The trend of young U.S. mobile users choosing to disconnect their home phone lines is growing, according to a report from In-Stat.

Use of mobile services is popular with young people with 47 percent of 15 to 18 year olds adopting them compared to only 17 percent of 35 to 44 year olds, according to a new report from JupiterResearch, "European Mobile Youth Consumer Survey, 2007: Targeting Digital Natives and Keeping Them Loyal."

AT&T has introduced a new Web-based feature that allows parents to stay in touch with their children while controlling the children’s mobile phone use.

Expect more than one mobile phone for every person in the U.S. by 2013, according to new data from SNL Kagan.

Mobile phone sales in the U.S. reached 33 million units in the second quarter of 2007, according to the NPD Group.

There are about 5.5 billion people on the planet. Roughly 2.5 billion of them use cell phones.

Only 1.1 billion surf the Web.

So when Vinton G. Cerf, who currently serves as Google’s vice president, states that mobile phones will fuel the growth of the Internet, well . . . maybe we should believe him.

“The mobile phone has become an important factor in the Internet revolution,” said Cerf. “You will get those other 5.5 billion people only when affordability increases and the cost of communication goes down.”
