I'm taking a wild guess that they are in the US as well. There has been a massive build-up to this day, and I think (hope actually) that Verizon will reward those loyal customers who have been with them for a long time (such as myself since 2005) with the iPhone well in advance of those persons who don't have Verizon Wireless accounts.
Oddly enough, Verizon and Apple will be taking orders on the 9th, with an in store pickup of the device on the 10th for all other customers. Now maybe I've taken entirely too many shots to the head from MMA matches but it seems to me that if I wasn't going to receive my phone early, then what was the sense of a pre-order if I can't get my phone sooner than the masses? Getting my phone shipped to me on the 10th (with a probable arrival date of the 11th) because I pre-ordered would put me getting my phone behind people that weren't currently Verizon Wireless customers. That, in my scrambled brains, makes no sense to me.
