Developers who want to test out iOS 6.1 Beta 5 on jailbreak software are in luck. Redsn0w still works.
This guide will help you jailbreak the following: iPhone 4, iPhone 3GS, iPod touch 4G
It works like the previous versions.
A few things to look out for:
– First, back up your iOS device.
– Don’t jailbreak if you use Ultrasn0w to unlock your iPhone.
– This is a tethered jailbreak. You must physically plug your iPhone into your computer any time you want to reboot it.
– You can’t jailbreak the iPhone 5, iPhone 4s, iPad 2, iPad 3, iPad 4, iPad mini or iPod touch 5G.
1) Download Redsn0w 0.9.15b3 (Dev-Team blog). Put that in a folder called Redsn0w on your desktop.
2) You will also need the iOS 6.0 firmware. We have it here. Just find the one that matches your device.
3) Plug your device into your computer via USB, and extract the application from the Redsn0w zip file. Launch the RedSn0w app within that folder.
4) If you’re on Windows 8, right-click on the Redsn0w.exe and choose “Properties.” Go to the Compatibility tab>Run This Program in Compatibility Mode for Windows XP. If your on version 7 or XP, just run as Administrator by right-clicking on the .exe file and choosing Run as Administrator.
5) Click on Extras
6) Click on ‘Select IPSW’
7) You will be told to select a jailbreak option. Choose Cydia.
8) Click Next.
9) Redsn0w will show you how to put your iOS device in DFU mode.
10) Your iOS device will reboot. It will reboot a second time, and Redsn0w starts to upload your new RAM disc and kernel.
11) Redsn0w will let you know when it’s done.
12) Click “ok” and “quit”
Every time you boot your device, you will have to run a tethered boot. It’s not much fun. it means plugging your device in, launching Redsn0w and going through the DFU process again. It doesn’t take as long as the actual jailbreaking process, because the device is already loaded with the custom IPSW, but it is definitely a pain.
