i think it gets pro-rated, oh wait, anything over the 12 month gets pro-rated, like i got a partial refund when i went from 7plus to XGonna wait until the 27th for my upgrade anniversary. Hopefully shipment dates aren't too bad by then.
With the IUP, the upgrade date is the date you purchase the new device right, not the day you activate it? So if I bought the phone now and it got here on the 28th, I'd still have to the pay $50 early upgrade fee from my X?
