I am only 15, my father hates in every way. To make things worse, he's a computer repair guy...im not here to complain that my father hates . I wan't an iPhone, it's $600 and it's something i'd totally buy, but my family has been giving me the hardest time saying it's a waste. I can careless, say if I bought the iPhone at AT&T today, even though I am 16 can I sign up for a contract? I have a credit card, I have a Social Security number and everything that's really needed on the form. My question is, do you have to be 18 to have a cell phone contract?
