Please forgive me if this has been covered. I, like many, am on backorder status. My local Apple store has phones in stock and before I reserve a time, wanted to ask something, since the guys at Tmo don't seem to agree on an answer. I have a credit towards my new phone, which will take 50% off the cost of a new iPhone 7 through TMobile. I am wondering if I can pick up phone at Apple and have the charges on my Tmobile bill, or will it be billed through Apple? Sorry if this is a dumb question. My gut tells me that I would need to buy the phone at a Tmobile store or wait for my preorder, but a rep at TMobile has me wondering. Thank you.
