Security and complexity are two of the issues surrounding so-called BYOD (bring your own device) policies in workplaces. AT&T is trying to address both with Toggle. It's not the only company with a system for dividing users' phones into two personalities. VMware and Red Bend, for example, offer virtualization software for phones, and Enterproid continues to offer its own service similar to Toggle.

Toggle 2.0 should be available for iOS in the next few weeks. Versions for the BlackBerry and Windows Phone OSes are coming by the end of this year, Cook said. Toggle costs US$6.50 per device, per month, plus implementation fees and optional managed services.
