It depends on how mature your parents think you are, how much money they have to buy an iPhone instead of a Samsung, and whether they think that is too easily stolen. Remember, people would much rather steal an iPhone than a $39 Samsung. I know some 12 year olds who would be fine with it, and others that I would not trust not to pawn the thing the next day.
