Posted this in the Waiting Room yesterday. Sorry for not posting here instead.
Well, the manager was there again today and told me he could see his POs (purchase orders) and was still expecting the devices to be there on the 26th. He showed me that they had already received the shipment of AT&T 950s, and even opened one to let me see it.
He said they also just got a memo that states the Display Dock offer is the same in brick and mortar stores as it is online. You will get a code when you purchase your phone. The "Lumia Offers" app is preloaded on the phone, and you can put the code in there or online. It's worth noting that he thought they would be handing out display docks, but after he read the memo fully (they had just gotten it earlier today, it seems), it said specifically that retailers should not give out display docks to pre-order customers.
He also revealed that only 5 people preordered the xl, and they were only getting enough units to fulfill the preorders. He said it could have something to do with the culture here not wanting to preorder. They also only received 5 AT&T 950s.
Anyway, that's pretty much all the info I got. It was enough for me, at least. I'll still be back tomorrow, just in case.
