AT&T Next 12 month-upgrade Question?
how is the uprade for the 12-month do i pay additional if i wanted to upgrade for the iphone 7?
so if i trade in my my iphone 6s will i get credit for the iphone 7 next plan?
since i already put down 509$ into next already..
is it worth upgrading this way?
im reading if i trade in my iphone 6 plus they will waived off the remaining installment plan and start with new next plan for iphone 7?
