BlackBerry, which released its Passport smartphone on Wednesday, has posted a smaller-than-expected quarterly loss.

Despite weakening revenue concerns, the Canadian phone maker reported a net loss of $207m for the second quarter of 2014. The previous second quarter results stood at a loss of $965m.

In a statement, CEO John Chen said: "Our workforce restructuring is now complete, and we are focusing on revenue growth with judicious investments to further our leadership position in enterprise mobility and security."

Chen, since joining BlackBerry last November, has manoeuvred the firm to build upon its software strengths, such as device management and its BBM messaging app.

Chen also revealed that the square-shaped smartphone, a device which could slam BlackBerry back into the enterprise device space, has received 200,000 orders since its release on Wednesday, and sold out on BlackBerry’s own store in six hours.
