<p>Apple has released an update that should resolve a bug introduced in iOS 6.1 which caused problems with Microsoft Exchange 2010 servers.</p><p>Users attempting to fetch emails or check the calendar on their newly-updated iPhones and iPads caused log files to swell and CPU and RAM usage on servers running Exchange to spike, severely degrading performance.</p><p>iOS 6.1.2 is now available as an over-the-air update for iPhone and iPad, but there is no mention as to whether it fixes a security flaw which can see just about anyone bypass the iPhone's lock screen.</p><p>An alleged loophole was posted on YouTube last week, showing how users could access the iPhone's 'phone' application with a few perfectly timed key presses. To exploit the loophole, users must cancel an emergency call before performing a number of button presses which should trick the device into keeping the 'phone' application on the device open. It appears as though the presses must be accurately executed, but if successful, this method will allow the hacker to make phone calls, view call records and other information such as contact details.</p><p><a href="http://www.techweekeurope.co.uk/news/apple-fixes-microsoft-exchange-problems-with-ios-6-1-2-108105">Keep reading...</a></p><p>Read also:</p><p><a href="http://www.macgasm.net/2013/02/19/ios-6-1-2-released-microsoft-exchange-battery-bug-busted/">iOS 6.1.2 Released, Microsoft Exchange Battery Bug Busted</a> (Macgasm)</p><p><a href="http://onsoftware.en.softonic.com/apple-issues-ios-6-1-2-to-fix-microsoft-exchange-bug-that-killed-batteries-and-consumed-data">Apple issues iOS 6.1.2 to fix Microsoft Exchange bug that killed batteries and ...</a> (OnSoftware)</p><p><a href="http://www.ubergizmo.com/2013/02/apple-releases-ios-6-1-2-to-fix-exchange-battery-drainage-issue/">Apple Releases iOS 6.1.2 To Fix Exchange Battery Drainage Issue</a> (Ubergizmo)</p><p>Explore: <a href="http://news.google.com/news/more?ncl=dy8BpDZ_q0_zuWM_glOdsEHRrg3QM&ned=us">167 additional articles.</a></p>
