The BlackBerry Q10 could sell ‘tens of millions’ of units, BlackBerry CEO Thorsten Heins has predicted as the QWERTY hosting handset receives its full UK release. The first BlackBerry 10 handset to sport the company’s traditional physical QWERTY keyboard, the BlackBerry Q10 follows on from the full touch BlackBerry Z10 as currently the only two BB10 handsets on the market. Rob Orr, Managing Director, UK and Ireland, BlackBerry, added: “The BlackBerry Q10 represents the next chapter in the BlackBerry 10 story and we are delighted that it has been so well received.
