BlackBerry posted a surprise profit for the quarter today. The Canadian company’s been struggling to stay relevant in the smartphone market but while the news is hopeful, it’s still too early to declare a turnaround.

Blackberry is back, with the launch of two new phones it hopes will revive the struggling smartphone company formerly known as Research in Motion. Facebook is working on best practices in an emerging area of social media -- suicide prevention. And, the military is using brain scans on new recruits -- canine recruits.

Research in Motion is set to release a new phone tomorrow, the Blackberry 10. Blackberry was once synonymous with the smart phone, and dominated the global market. But in an iPhone and Android world, Blackberry's market share has shrunk to less than 10 percent in the U.S.

Google's Android and Apple's iPhone are vying for number one and two in the smart phone market. BlackBerry comes in third with 11% of the market and 90 million users around the world, but just who are these users?
