The iPhone Dev Team has released RedSn0w 0.9.13dev1 to jailbreak the iOS 6 beta for select iOS devices. This jailbreak is made specifically for developers only so it will be different than your average jailbreak, as this will not add Cydia. With this jailbreak, you can use SSH and any other iPhone file navigation app/utility.
- iPhone 4
- iPhone 3GS
- iPod touch 4G
Notes before Jailbreaking: This is a tethered jailbreak, it will not install Cydia on your device, it will not hacktivate, and if want to preserve the baseband, stay away.
Step 1: Download and open RedSn0w 0.9.13dev1
Step 2: Navigate to Extras > Select IPSW > point to your iOS 6 firmware file for the selected device
Step 3: Click the Back button and then click Jailbreak
Step 4: Put your device into DFU mode and then the jailbreak should begin. Once RedSn0w asks if you want to Install SSH, make sure you check that option and click Next
Step 5: Once your device has rebooted, go back to RedSn0w and click Extras > Just Boot. This will perform a tethered boot, which you also have to do every time your device turns off
Step 6: Congratulations, you are now jailbroken on iOS 6 beta firmware
