BlackBerry has said that one of its “established partners” has placed an order for 1 million BlackBerry 10 devices. Without naming the company, the Canadian smartphone maker said that this is the single largest order in the company’s history. The order, according to BlackBerry, is for both the Z10 and the Q10, but no further detail were revealed.

“An order for one million devices is a tremendous vote of confidence in BlackBerry 10,” said Rick Costanzo, EVP Global Sales, BlackBerry. “Consumers are ready for a new user experience, and BlackBerry 10 delivers. With strong partner support, coupled with this truly re-invented new platform, we have a powerful recipe for success.”

BlackBerry’s shares jumped 8.2 percent, to $15.65, at the New York stock exchange, after the announcement. BlackBerry’s stock has already climbed 32 percent this year, after a series of positive developments leading up to the BB10 launch. Meanwhile, customers in the U.S. will be delighted that Verizon has now started taking preorders for the Z10.
