How old were your kids when they got their first smart phones?
My oldest kids (twins) bought their own smart phones (Samsung Galaxies) when they were about 20.
I gave my middle son a used iPhone 5 when he was 17.
I gave my youngest child (a girl) my old iPhone 4 when she was 13.
Around here, it seems like all her friends have brand new iPhones or the very latest model of an Android phone. It's nuts. (We live in an expensive, hoity-toity area . . .)
When did you give your kids their first smart phones? Or did you?
