BlackBerry

BlackBerry is a family of smartphones and the related operating system from Research in Motion. The BlackBerry is the most popular business handheld device. When paired with the Blackberry Enterprise Server, the Blackberry enables secure mobile e-mail, voice, Web and other data services. The device, which has earned the sobriquet "crackberry," is under attack from Nokia, Microsoft and others. There is an incipient threat from the iPhone, but so far Apple has sent mixed messages about its attitude toward the corporate market.
