Just got off the phone with AT&T and Apple.. If you're NEW to AT&T NEXT and preordered an iPhone (whichever size) on Apples website, you'll have 14 days to return the phone to any Apple or ATT store. If you preordered through ATT - it has to go back to a corporate ATT store. You won't be charged your first installment even if the phone is activated (so long you bring it back within 14 days. You're upgrade and Next eligibility will return once the phone is back at apple or AT&T. (Pretty much like nothing happened - i.e before you pre ordered) So I thought I would throw this out there for any one who might have second thoughts on their new phone (6 or 6 plus). Who preordered and signed up for a new next plan. I don't know how it works with existing next plans who are doing trade ins. Cya!
