So far in my area of in Ohio various Best Buy stores have them. I had called a couple carriers on the announcement day and they weren't expecting them in for a few days they very well may have some now
The T-Mobile store here had them on display. It was nice to get to play just a bit before I ordered. I hated the cord attached because I couldn't really get the feel of it in my hand.
edit: Sorry, by "here" I meant just north of Dallas.
