On Wednesday, BlackBerry unveiled its newest smartphone with a full physical keyboard and a large screen. Aiming to return to its roots, the features of the new smartphone mostly targets business users. The BlackBerry Passport, named for its approximate size to the travel document, is designed to win back key corporate users after the company struggled in the competitive consumer smartphone market dominated by Apple and Samsung. The Passport made its global launch under chief executive John Chen at events in London, Dubai and Toronto. The Passport is the third of four new phones to be launched by BlackBerry this year. The first was the Z3 smartphone that was launched in Indonesia followed by the Porsche-designed phone sold in Dubai. The Blackberry Passport will be released in stores within two weeks.
