Not in your area; but the Northern Virginia Apple Stores were very helpful in letting me know on Saturday evening they were getting them in on Monday. My Apple store of choice that day was Reston... with them saying that they would get them at 12 noon. Showed up at noon with 10-15 people waiting.
Evidently the delivery or check in was late, we were left waiting till about 12:15 till the first person was helped. Most of us seemed to be switchers from an older iPhone or another phone on ATT and did not want to be out of touch with our cellphone service till we could get home and setup the iPhone service at our leisure later that day (to get the discounted price your current ATT cellphone is deactivated until you have your iPhone 4 up and running).
Though in an hour I was out of the store with my new iPhone 4 🙂
