A History of Enterprise Management Improvements in iOS
Jack Madden has written a helpful history of enterprise management improvements in iOS.
"As we gear up for Apple's WWDC in June (with fingers' crossed that we'll get even more enterprise management features in iOS 7), I thought it would be good to take a look at just how far Apple has come over the years when it comes to improving the enterprise management aspects of iOS."
Although it isn't their marketing focus, enterprise iOS is a significant part of engineering. Every major release of iOS has included some features useful only for people like us.
