Other than paying for a new iPhone in full, is there anyway to purchase a new iPhone but not activate it right away? I am looking at taking advantage of one of the iPhone 7 deals this weekend as a Christmas present for my dad. I don't mind starting the device payment plan now, but I would like to keep his old iPhone active until Christmas so that I could wrap the new one up and put it under the tree. Is this possible, or do they force you to activate the new phone right away?
