Yup! No stickers for that, but a bunch of the tables at a sensible place in your store (either at the genius bar, or another place where they can easily fence it off with security guards!) and they'll have stacks of each phone they have stock off. There's enough for every reservation and every walk-in business card which is stickered with a SKU (and to be honest, they might well not bother stickering the paid ones, and just grab it!)
You'll be assigned to a staff member when you enter the store, and they'll get you going on their POS device (the funky rectangle with a barcode scanner on the top and an iPhone/iPod Touch inside it). At some point in the process, they'll scan the QR code on your email (for reservations) and then send a notification to someone else's POS device who will grab your phone and deliver it to whichever table your Apple Store employee is sat at. They have a little dropdown where they have to pick the table they want it delivered too.
It's a very efficient process

Yeh exactly! They might well not even stick the sticker onto an iPhone so they don't have to bother finding your exact phone and can just get you one from the pile. It's all stock controlled so they isn't any risk of them selling more phones than they have in their piles
I do love the atmosphere of an Apple Store at 8am on a launch day. Especially now we have reservations and there isn't a fear of not getting a phone in a long queue.
