Apple will soon be releasing iOS 6.1.3 which once again will prevent the ability to jailbrak your iOS device. If you have been putting off upgrading to 6.1.2, we are moving into the last days of being able to do so before Apple closes this window of opportunity. Unlike jailbreaks of the past you are not able to install an older OS version once a new version is released. This means that once 6.1.3 is released if you ever have to do a restore you will go back to being un-jailbroken and will stay that way until a new jailbreak method is discovered.
You can download the latest jailbreak that covers all current iOS 6 versions via this link..
