There is a difference between a commercial partner like DNA and the "normal" preorder. I doubt that DNA had to go through the regular preordering proccess like we did.
And even if they did preorder in whichever way, at least it should have been stated clearly by Jolla that DNA will have priority over non-finnish preorders. But from Jolla's statements it always was like "Preorders in supported countries get served first", at least thats how it came across to me from their vague statements

Well, they still have a day to get the shippments out to the supported countries if Wednesday is correct for DNA to start selling.. so lets wait and see (not much we can do about it anyways)
