The Blackberry line of smartphones are created by a Canadian company named Research In Motion (RIM). They are run on a proprietary operating system and can be integrated into a company's email system through RIM's own Blackberry Enterprise Server (BES). Blackberry devices earned the nickname "Crackberry" to signify their seemingly addictive features.
