[From Kwane's iPhone 4S] I been using my iPhone since 2007. I still have the first gen. And I also have the 3Gs, 4, and 4S. I love the ease of use with the IOS system. It's user friendly and kid friendly too. My son it six and he uses my first gen. iPhone to learn numbers and reading on it. He uses it everyday. He learning Spanish and Sign language with it daily. I think Apple has created a wonderful media to help teach our children with in this day in time.
