BLACKBERRY LTD. $10 - Toronto symbol BB

BLACKBERRY LTD. $10 (Toronto symbol BB; Aggressive Growth Portfolio, Manufacturing & Industry sector; Shares outstanding: 527.0 million; Market cap: $5.3 billion; Price-to-sales ratio: 1.1; No dividends paid; TSINetwork Rating: Speculative; www.blackberry.com) has won approval from the U.S. Defense Information Systems Agency for changes to its server software. These upgrades will let employees of businesses that work with the U.S. Department of Defense use non-BlackBerry devices, including the Apple iPhone and phones powered by Google’s Android software.

Adapting its mobile data systems to securely handle competing phones should help BlackBerry hang to its big government and corporate clients.

BlackBerry is still a hold.
