It’s just a couple of days that Apple has come up with iOS 6.1.3.
and the Hackers have followed a security hole.
which allows anyone to bypass the passcode lock on iPhones, and access private data like contacts and images on the device.
it can simply be done if you have physical access to the device and widget to access sim tray.
You don’t need to worry such a flaw cant be removed BUT you can surely prevent anyone’s access to your phone.
all you need to do is follow following steps~
go to settings>General>passcode lock>then disable the voice control panel.
your device can not be authorized by anyone now.
This one is for those who are very keen to update anything—
if you update your apple device with iOS 6.1.3
then your jailbreak freedom will be jeopardized.
Update has patched several holes that Evasi0n exploited to perform an untethered jailbreak on all iOS devices, including the latest iPhone,iPad and iPod touch. People who upgrade to iOS 6.1.3 will no longer be able to use Evasi0n to jailbreak their devices.
And once on 6.1.3, newer Apple devices cannot be downgraded to a previous iOS version.
so be careful with your updates.
