That new capability is still under development for an unspecified date on AT&T's road map. But, along with other enhancements announced on Wednesday with Version 2.0 of Toggle, it could make the service into a broader platform for remote work. Toggle 1.0 was announced last October for Android devices. Now it is set to ship for Apple iOS in the next few weeks and for BlackBerry and Windows Phone by the end of the year.

Toggle combines a service for enterprises with an app for downloading to consumers' own phones, tablets and other clients. The app divides a mobile device into a personal mode for the usual consumer apps and a secure, encrypted "work mode" just for apps and content approved by an enterprise. Employees can switch to the work mode while on the job and go back when the day is done. It's designed to help companies implement BYOD (bring-your-own-device) policies while protecting themselves.

The new version transforms Toggle from a system built around pushing corporate resources out to employees' devices to one that lets users go to a customized site and download approved apps and content. AT&T even went to a different mobile-device-management software partner, OpenPeak, to develop the new version. Its , which the carrier developed with Enterproid, is still available and supported.

AT&T will be moving toward a resale relationship with Enterproid, which offers the Toggle 1.0 technology under the name Divide, said Chris Hill, AT&T's vice president of advanced mobility solutions. AT&T is the exclusive carrier provider of the OpenPeak technology underlying Toggle 2.0.

While the addition of iOS support is a major step in the mobile arena, porting Toggle to PCs and Macs could bring it into another large pool of workers at home and on the road. Those users could access their work applications securely on a personal machine without using any mobile network because the software works on any Internet connection type.
