How old should you be to have.a phone/iPhone

How old

Added (1). Wow! You guys are crazy! I had my 1st phone when I was 8!

I say teens at least. 13+

Old enough to be able to pay for it and be responsible enough to use it. There's no one age. Based upon my second criteria I would say at least 18, the age I was when I hit my first phone, (25 now) but some mature at different ages. I know some 30 year olds who I don't think should have phones. If they can behave with it, then why not let them have one now?

High School

13+ depending on how responsible a kid is I'm not dishing out money if its not gonna get taken care of.

10+ because it teaches them to be responsible and they won't be bugging their brother and sister.
