RIM leads 'bring your own device' market Research In Motion, VMware and Red Bend Software are working to give phones a split personality, seeking an edge in the emerging market for tools that let employees use their own gadgets on the job. RIM in coming weeks will unveil an enhanced version of BlackBerry Balance, software to help employees seamlessly use their smartphones and tablets for work tasks without compromising their privacy. The software also promises to help businesses cut security risk and save money on hardware and device management. With the tap of an icon, the phone's home screen will switch from showing personal wallpaper, contacts, schedule and applications such as Facebook to a business screen, with only an employer's apps and contacts, all secured and managed by corporate engineers. [...] installing dual-personality software may emerge as the most popular way to make devices serve both purposes, said Chenxi Wang, an analyst at Forrester Research. [...] split-personality phone and tablet software - just one piece of the spending by corporations and individuals to enable work-related use of mobile devices - could spawn a new, $1 billion market in as little as five years, Wang said.
