I managed to do this, but somehow I don't think it'll fly on pickup day.
Reserved 1 phone shortly after 1am PST before all the madness ensued. Got the confirmation email, and clicked the link "Cancel this reservation". That link brings you to a screen where you can "Edit this reservation" at which point you can add an additional phone to your reservation. Didn't try adding an additional one though.
