Apple has backtracked on a prior decision to change the way VPN On Demand connects in iOS. An updated support article notes that “Apple no longer plans to change the behavior of the VPN On Demand feature of iOS 6.1 for devices that have already been shipped.
The ‘Always’ option will continue to work as it currently does on these devices.” Previously, Apple announced VPN On Demand configured to “always” would behave as “establish if needed.”
The initial change was made due to a patent suit loss to VirnetX; there’s speculation that because of Apple’s reversal on the VPN issue, the two companies have reached some kind of agreement. Notably, because Apple only mentions devices that have “already been shipped,” the changes still might be made to as-yet-unshipped items.
