It just occurred to me that two nearly identical iPhone 5's will be arriving on Friday (hopefully). They are both black and slate, 64 GB, and AT&T. What's worse, they both have the same ship-to name and address, even though they are for different people and different phone numbers. Same: Address Ship-to name Different: Bill-to name Bill-to address Phone number How will we tell the difference? Does it matter, or can we activate either phone with either number? Thanks.
