I want to purchase an iPhone 5s for a family member of mine for Christmas.(AT&T) I'm planning on purchasing this phone at an Apple store either on Friday or on Monday of next week, but I have a few questions. The last time I bought an iPhone at an Apple store, my old phone was automatically out of service (even though my new iPhone was still sealed!) Obviously I don't want my family member's phone to be out of service when I purchase their new phone. (They'd be suspicious that I got them a new phone) Is there anyway to make this a surprise? Also, do Apple stores support AT&T upgrade swaps?
