The Nokia X did not have 1 million pre-orders in China
It looks like the news that the Nokia X achieved 1 million pre-orders in China is false.
RetailerJD.com set up a contest where participants could hit a “pre-order” button for a chance to win a Nokia X. The pre-orders didn't require you to register with the site or put any money down, which is not the norm for China.
This doesn't mean that the sales for the Nokia X will have difficulty reaching this number. The handset will be retailing for $100 unlocked, which is really cheap for a smartphone. Also given the fact that the X is Nokia's first Android smartphone, expect it to sell fairly well.
It doesn't change the fact that the numbers were fudged, or, at best, were misleading.
