20 September 2013 Last updated at 21:39 BST

Blackberry announced on Friday that it would cut 4,500 jobs, or 40% of its worldwide workforce.

It also said it anticipated a loss of as much as $995m (£621.1m) when it reports its second-quarter earnings next week.

The firm had pinned hopes on the launch of the Blackberry 10 earlier this year but sales have been weak.
