Downgrade iPhone Running ios 6.1.3 to ios 6.1.2: Currently we cannot support this process. It is very complicated and requires some extra research to complete the process. Not all phones will be able to be downgraded. The best thing to do is not update the iPhone to 6.1.3 until there is a stable untethered jailbreak, and a stable carrier bundle and commcenter patch created. Please follow these instructions carefully, and use google to find any information that you need.
Again, if you happen to be on iOS 6.1.2, DO NOT update to iOS 6.1.3, or you will lose your untethered jailbreak. This tutorial applies to users of pre-A5 powered iOS devices only, who may have accidently updated to 6.1.3, or those developers who want to test their tweaks and apps on 6.1.3 for any future public untethered jailbreak release.
The update, which has seen various beta releases over the past months, and by various, we mean a lot, brings with it a slew of new features and, perhaps more importantly, fixes to existing issues, making the overall user experience more worthwhile. Some of those issues may seem rather minor, whilst others are biggies, especially if they happened to affect you!
How-to Jailbreak iOS 6.1.2:
Step 1: Update your device to iOS 6.1.2 using iTunes (download iOS 6.1.2 from here): if you are jailbreaking your device, why not update it to the latest version of iOS? OTA updates might mess with the jailbreak, therefore a fresh restore via iTunes is strongly recommended.
Step 2: Turn off Passcode Lock in case you have it enabled. In order to do this, simply head on over to Settings > General > Passcode Lock > Off.
Step 4: Start up Evasi0n on your computer and simply click on the “Jailbreak” option. Kick back or grab a cup of coffee as Evasi0n does its work and jailbreaks your device. Remember not to touch anything while your device is being jailbroken.
Step 5: Once this is done, your device should boot straight back. You will see a new Jailbreak icon on your home screen. Tap on it in order to finish the process.
Step 6: Your device will now reboot quite a few times for a short while, before it boots into the jailbroken state. Once this is finally done, your device should boot back in a jailbroken state.
You are done: if everything has gone as expected, Evasi0n should indicate that the jailbreak is complete. Cydia should now also be on your home screen.
Soon after the release of iOS 6.1, it came to the attention of the tech world that a major security flaw allowed basically anybody with a spare couple of moments to slip through the passcode system and access a device’s confidential, and supposedly secure data. The release of iOS 6.1.1 a couple of days back, which fixed lingering cellular and battery issues with the iPhone 4S, is also susceptible, and an urgent update is required on all fronts to sort this mess out. According to iFun, a German blog which accurately pinpointed the aforementioned 6.1.1 release, reckons that will likely be “early next week”, meaning those conscious as to the security of their iPhone will only have to wait a couple more days.
