4) Open up CMD, right click and run as administrator and type (Without ” quotes) “cd downloads”

5) Then type: cd cinject_0.4.3

6) Next type this command  cinject.exe -i payloads/jailbreak.mobileconfig

7) On your device, click on install, and when prompted to type in a password, just click next, with no password in.

8.) Now back to the PC and type this command: cinject.exe -j payloads

9) Just wait, might take some time.

10) Now type this command:  cinject.exe -w

11) On your device toggle the “VPN” switch on in the settings, after a few seconds it should say “error”, this is ok

12) Now reboot your iDevice. Cydia should be installed.

How to Jailbreak the iPhone 4S or iPad 2 with Absinthe

Step 1: Download, extract, and run Absinthe from here.

Step 2: Connect your iPhone 4S or iPad 2 via USB.

Step 3: Click “Jailbreak” to run the Absinthe jailbreak. It will take a while on the beginning portion, and eventually your iPhone 4S or iPad 2 will look like it’s restoring a backup. It will say “Restoring in Progress”. This can be pretty lengthy. Don’t worry, it’s working. Don’t touch your device until completely finished!

Step 4: Once completed, unlock your iPhone if necessary, and you should see an Absinthe icon on the Home screen. You may have to search for it if you have a lot of app icons. Tap the Absinthe icon, and it should load the GreenPois0n site, and will then reboot your device. Once it loads back up, the Cydia icon will have replaced the Absinthe icon.

Step 5: Your iPhone 4S or iPad 2  is now  jailbroken! It took a while, but it was certainly worth the wait. Now all that’s left to do is load Cydia for the first time, and start downloading your favorite jailbreak apps and tweaks.

Some users are experiencing errors with a message saying “Error establishing Database Connection”.  Here’s what you do:

iOS hacker PlanetBeing who helped develop the jailbreak tweeted a simple fix for the “error establishing a database connection”. Apparently, all you need to do is go to Settings > Network > VPN > ON.

The VPN connection will most likely give an error and your iPhone 4S or iPad 2 should reboot shortly after. Once it’s rebooted, try launching the Absinthe webclip again.

That should do the trick.

Comex has released a fix for a JailbreakMe bug that could cause Verizon iPhones to get stuck at the Apple logo and be unable to boot.

If you are in this situation, there are two options:

1. Hold down the home and power buttons until you see “Connect to iTunes”, then use iTunes to restore to the latest firmware. This will lose data stored on the phone.

2. Apply a quasi-experimental fix using redsn0w. Download:
● redsn0w 0.9.6rc19: Windows / Mac (do not use an earlier version)
● Fix bundle, depending on firmware version: 4.2.6 / 4.2.7 / 4.2.8
● IPSW for your firmware version, if you don’t have it: 4.2.6 / 4.2.7 / 4.2.8

To perform the fix:
Open redsn0w, select your IPSW, choose “Install custom bundle”, and select the fix bundle. Then follow the directions. If it works correctly, after installation your phone will boot normally.

There is a separate bug where choosing “Re-jailbreak” would cause a device to be unable to boot. If you have this issue and don’t want to restore, you can contact comex via Twitter @Comex.
