Not too long ago, Apple released iOS 6.1 to the public, yet this one was plagued with issues ranging from a lock screen exploit to numerous connectivity problems affecting Microsoft Exchange users. While the recently released iOS 6.1.1 update for the iPhone 4S, which Apple rushed quickly, addressed the critical connectivity issue which stopped many business users from upgrading, this new 6.1.2 release fixes many other small problems that were still left.

iOS 6.1 included quite a few additions and small changes when compared to the original release of iOS 6 in order to address customer feedback and make slight improvements to the overall user experience. Among these changes, a slightly updated Music app was introduced featuring new, more polished controls, LTE “4G” support in more European, African, Asian and American countries, improvements to Siri and small changes to the initial setup wizard. This release was followed weeks later by iOS 6.1.1 for iPhone 4S, which addressed a critical flaw in network connectivity.

However, a critical exploit was quickly found which allowed unintended users to get past the passcode protected lock screen of any iPhone by spending a few seconds meddling with the Emergency Call feature. While this is not easy to perform by accident, this vulnerability could place an unsuspected user’s contacts at the hands of an unintended user. This bug has been reportedly addressed with iOS 6.1.2, hopefully before major pranks were played all across the world involving unsuspecting contacts stored on a victim’s phone.

Other than that, the Exchange bug has also been addressed with the release of iOS 6.1.2. Here’s what the official change log says:

Fixes an Exchange calendar bug that could result in increased network activity and reduced battery life.
