Kids getting cellphones at younger ages

Quick, take a guess: what's the average age American kids are getting their first cellphones? 10? 12? 14?

According to data out today from the Pew Internet & American Life Project, most are 12 or 13. But hold on, there, before you go ripping the phone from your 10-year-old's fingers. According to Pew, while none of the 17-year-olds in the survey got phones when they were 11 or younger, more than half of today's 12-year-olds had phones when they were 11 or younger.

So, the times are a'changing, and it appears most parents today think it's ok to give their kid a phone by the time they turn 11. What do you think? When did your kid get his or her first phone? Are 11-year-olds mature enough to have cellphones?
