Mark ordered an iPhone X from Apple and he's worried about the order. He ordered an AT&T model, but his wife moving to Verizon. Can he swap it through the Apple store? Leo says that's probable. He'll definitely want to do that since the phones are locked to the carrier. The Verizon model would work with AT&T, but not the other way around. That's because Verizon's phone is unlocked, but have different radios in each. Leo suggests not even opening the box. He should just take the phone to the Apple Store and swap it out. They have enough of a supply now, so there shouldn't be a problem.
