Apple releases iOS 6.1.2 to fix Exchange Calendar bug
Apple released iOS 6.1.2 to fix exchange calendar bug in iOS 6.1.1 that could result in increased network activity and reduced battery life.
Apple earlier acknowledged the Exchange bug in its latest mobile operating system (OS) when Microsoft blocked iOS 6.1.1 users from accessing Exchange Servers due to issues that led to over-polling on mailboxes and calendars.
We got customers asking if Codeproof can block iOS 6.1.1 updates. Unfortunately iOS MDM protocol won’t allow Codeproof to block system updates.
