One in 10 of these preteenagers has responded to and chatted online with strangers, according to the Tween Internet Safety Survey, sponsored by Cox Communications and the National Center for Missing and Exploited Children.

90 percent of American kids have used the Internet by age 9 and more than a third of 11- and 12-year-olds have a profile on social-network sites such as MySpace and Facebook.

Of the tweens with social-network profiles, 61 percent post personal photos online, 48 percent admit to posting a fake age online and 51 percent have received messages from people they didn't know.

The fact that cell phones pose a great risk when combined with driving cannot be of any surprise to anyone. Let’s face it. First, drivers must take their eyes off the road while dialing. Second, people can become so absorbed in their conversations or other cell phone use that their ability to concentrate on the act of driving is severely impaired, jeopardizing the safety of vehicle occupants and pedestrians alike.

Mounting Minutes ($$$) Since consumers must be 18 in order to purchase a cell phone contract in the United States, most parents are buying the phones their children carry. This is good news because parents can choose a plan that fits how the cell phone will be used and can review monthly cell phone bills which typically includes a log itemizing phone activity.

She's part of a young generation of fashion bloggers who display their outfits for all to see. "Well I am new here," she wrote March 31 in her first post at Style Rookie.

Along with marketed content for the PlayStation Portable, Nicolakis said Playboy started a service called iBod. The service started in 2005 and allows users to download soft porn to their device. Wallpaper of nude photos and explicit ring tones are some of the other materials available through built-in Web browsers in portable devices like the iPhone, Nicolakis said, and parental safeguards are nonexistent or just now becoming available. He said another avenue for pornographic material is user-generated photos or videos sent from cell phone to cell phone. Teens are reportedly taking sexually explicit photos of themselves and sending them to friends, but the images can easily be sent without consent to others, Nicolakis said. "That's child pornography, and that's a felony," he said. "If you think you're immune to it here in Modesto, you're wrong. It's probably already happened, you just don't know yet.
