Jailbreak iOS 6.1 Beta 1

1. Download iOS 6 from here. Download iOS 6.1 beta 1 from iOS Dev Center. Update your device to iOS 6.1 beta 1.
2. Download and run Redsn0w 0.9.15b3 (Windows/Mac).
3. Navigate to Extras –> Select IPSW option and manually point Redsn0w to the original iOS 6 (not iOS 6.1 beta 1) file.


4. Now from the main screen of Redsn0w, simply click on Jailbreak, followed by Next to select Cydia. Enter your device into DFU mode with the help of onscreen instructions on Redsn0w.
That’s about it. Redsn0w will now automatically inject your device with Limera1n exploit to jailbreak and install Cydia on it. Once done, select “Autoboot this device when it connects in DFU mode” to restart the device in tethered boot mode.
Since this is a tethered jailbreak for iOS 6.1, you will always need to reboot your device into tethered mode in order to run Cydia and other jailbreak related apps. Whenever your device loses power, simply connect your device to your PC or Mac and start Redsn0w. Navigate to Extras and then just use Just Boot option to boot into tethered jailbreak mode.
