Intelligence, not age. (Score 1)

Age is no measure at all of a person's ability of using a cell phone(or anything else). Let's face it, most people make us wish they didn't have access to the technology we use. But it is also the only way for improvement. The new generation is growing up with technology. Sure it was great when the Internet wasn't swarmed by idiots, but at least those idiots are hopefully learning at least something from being on the Internet. Children should, from the beginning, have unrestricted access to all information - that is the only way they can learn how to handle it. Shielding them from the world won't make them ready for it. If you are looking to bring up a helpless, defenseless kid that will fall victim to the first person with not so great intentions - go ahead and shield them. It is nothing but a perversion of the human mind to keep control over others, and make them dependent on you. So the right age to use a cell phone? Forget the age. Take the IQ instead. And apply it to everybody, not only kids.
