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.

iOS 6.1.2 is out to iPhone, iPad and iPod touch users.

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 affects of the bug also caused the battery life on the iPhone or iPad to suffer significantly. 

Microsoft came up with a few ideas to prevent the overloading, such as switching off the calendar function altogether or simply banning all iOS 6.1 users from accessing the network. 

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.

But Apple then said it would fix yet another issue—this time a security bug that allows anyone to bypass the security lock screen on the device with a few steps.

After this update, we tried to bypass the lock screen using the same method as described last week and were unable to, suggesting that it had been fixed. However Ars Technica reports that they were able to bypass the lock screen even after the update, suggesting that it has yet to be fixed.
