Default US backer here with a 512/4GB model

So I got my watch today, and it has a NA baseband and makes calls over Tmobile, but only have 512 ram and 4gb storage.

Omate said ALL North American backers would get 1gb / 8gb (I actually paid for a 1gb/4gb) so it is odd, since I didn't even think they MADE any 512/4gb NA models.

Anyone else get a 512/4 model in North America?
