I found this post on Reddit:
http://www.reddit.com/r/apple/comments/1mcu0x/apple_store_will_do_att_upgrade_swaps_cross/
The Redditor explains that their systems were just upgraded and "now they can do everything in one swoop without any new SIMs or calling the carriers for AT&T and Verizon".
Besides this one post, I haven't heard anything about this. Can any other Apple employees here confirm this? Thanks.
