Apple today released iOS 6.1.2, the latest iteration of the mobile operating system for iPhones, iPads and iPod touch devices, following widespread reports of errors caused by calendars connected to Exchange servers.
Both Apple and Microsoft began investigating reports that those running iOS 6.1 update caused overloading on corporate Exchange email servers. Some enterprises complained that their newly updated iPhone or iPad were “causing excessive logging” on the server. As soon as the iOS 6.1-powered device was switched off, the problem mysteriously went away.
But the effects of the bug also caused the battery life on the iPhone or iPad to suffer significantly.
iOS 6.1.2 arrives on shiny rectangles of multiple sizes just over week after iOS 6.1.1 was released, which fixed cellular performance and reliability problems for iPhone 4S users.
Some iPhone 4S users in Europe complained that the latest upgrade caused cellular and 3G networking to degrade. U.K. and European carriers sent out text messages to customers warning them not to update to the latest version of the mobile platform as it was causing their own networks to suffer.
After this update, we tried looking the TMG logs for “cmd=meetingresponse” and found no repeating logs, suggesting that it has been fixed.
