How to Jailbreak iOS 6 Beta 3 on A4 Devices Using Redsn0w 0.9.13.dev3

Step 1: Download Redsn0w 0.9.13dev 3 for Windows

             Download Redsn0w 0.9.13dev3 for Mac

Step 2: Download and save iOS 6 beta 3 firmware file (IPSW) from Apple's developer Web site.

Step 3: Put the iPhone, iPad or iPod Touch into Device Firmware Update (DFU) mode. Follow these steps

• Plug iPhone, iPod Touch, or iPad into Mac or Windows PC while ensuring iTunes is running
• Simultaneously press both the Sleep button (on top of the device) and the Home button (on the front underneath the screen) and hold for 10 seconds (If you see the Apple logo, you've held them too long and will need to start over)
• Release Sleep button but keep Home button pressed for about five seconds (If you see the Plus into iTunes screen than you held it too long and will need to start over)
• If the screen stays black, the iPhone, iPod Touch or iPad has entered DFU mode 

 Step 4: Now launch Redns0w and tap Extras

Step 5: Tap Select IPSW, browse to location of the IPSW file for iOS 6 beta 3  downloaded in Step 2 and select it

Step 6: Return to main screen of Redsn0w tool and click Jailbreak

Step 7: Ensure Install SSH option is checked and click Next

How to Perform Tethered Boot

Since the developer version of the Redsn0w tool supports only tethered jailbreaks, you need to perform a tethered boot after the jailbreak has been successfully installed.

Step 1: Put iPhone, iPad or iPod Touch into DFU mode again

Step 2: Return to main screen of Redsn0w, tap Extras again and then click Select IPSW

Step 3: Navigate to iOS 6 beta 3 file and select Just Boot from Extras menu

At this moment, Redsn0w will reboot and bring up your desktop screen without the Cydia option. However, if you are keen on running third-party apps and tweaks with the beta operating system, then you could install .deb files using afc2 or SSH command line interface as an alternative to Cydia.
