We're in the same boat Pat. Same exact model as well. I was in this thread a lot earlier. I tried to get the store to cancel my pre-order around noon at the Westfield NJ store on Friday but they wouldn't. Not sure if they've since changed their stance, as a lot of stores are now canceling back orders and giving iphones from their stock now that they realize the ridiculous and unfair manner they treated their best customers. And they never got the rush on their stock (much of which they should have allocated to the in-store pre-orders!) anyway.
If I were you and you were really eager to get it, go to the store you ordered. They may well have 64's left. Then show and tell this thread. It says it all!! But calling corporate or emailing will get you nowhere, don't bother.
I may do the same, but I'm tied to the office for now.
