Hi, Do any of you know the best financial way to sign up with at&t as a new user, get a free phone, sell the phone, and upgrade the plan to the iphone? i want to get a family plan with 2 iphones. what free phone should i get to get the best resale value? sell on craigslist or ebay? if i want a family iphone plan (2 phones) should i sign up for a family plan to upgrade with 2 free phones? do i have to active the free phones, or can i leave them all boxed up brand new and still upgrade to the iphone plan? thanks.
