Ma Bell is hoping to expand its array of business-friendly (or more accurately, IT-friendly) smartphones in its collection. The company this week unveiled AT&T Toggle, software that will allow Android devices (2.2 and above) to switch into a more secure "work mode" for using corporate email, apps, calendars, and the like. IT managers will have tools for managing employee access, adding / updating / deleting work-related apps on the employee's device (presumably only those related to work mode), and wiping all corporate information stored in work mode.
