I've asked this question before, and got the answer of, yes you can. However, this morning, I was woken up by my dad calling me all the way from Florida (I live in CA), and he tells me, he just bought the Instinct on tat $99 everything plan. I was just going wtf? I asked him how come he's not doing the family plan with AT&T and doing a $150 a month plan (2 included plans 2 iphones?). He tells me that he's looked into it, and you just can't do it at all. So now, I'm just so completely lost.
