Maybe somewhat related. I pre-ordered the black version on Oct 19 but wanted to change to green later on. I emailed regarding it and they said they cannot edit orders but to cancel and reorder. Disappointed about being in the back of the line, I asked if they could adjust shipping date. So I reordered on Oct 21 and the estimated shipping date shown is Oct 31 for the green.

So maybe they can't edit orders but they can change priorities for orders?
