There is no reason for Apple to withhold the sale of white iphones.  If they were available, they would be available for preordering/reserving.  Why would Apple effectively decrease their number of sales and revenue?  Nothing would make Apple happier than breaching the 1 million sales in a day milestone.  There is clearly a production issue.
