An anonymous reader writes: Today BlackBerry announced that it expects its quarterly net operating losses to be somewhere between $950 million and $995 million. It also confirmed earlier reports that it would be cutting 4,500 jobs, roughly 40% of its total workforce. 'The loss is mainly the result of a write-off of unsold BlackBerry phones, as well as $72 million in restructuring charges. The company said that it would discontinue two of the six phones it currently offers.' According to the press release BlackBerry is going to 'refocus on enterprise and prosumer market.' 'The failure of the BlackBerry 10 line of phones quickly led to speculation that the company, like Palm before it, would be broken apart and perhaps gradually disappear, at best lingering as little more than a brand name.'
