With the new school year getting under way, parents are expressing concerns about Internet safety as well as their children's cyber behavior. Nearly 90-percent of those taking part in a new Awareness Technologies poll say they've discussed Internet safety with their kids, but 40-percent admit they don't know if cyberbullying is an issue at their children's school. However, only 20-percent say cyberbullying is their biggest worry. Four out of five parents say they're most concerned about their child using the Internet or their cell phone for sexting and other inappropriate online activities. Just over 50-percent are worried about online predators. More than three-quarters of the parents polled say their children have their own phones. Four in ten students have a basic mobile phone, but 20-percent carry Android devices and 18-percent have iPhones. Twelve-percent have a BlackBerry.
