Update. A new version of greenpois0n RC5 is available. This version fixes all the bugs found. However the saurik and chronic dev team servers are always saturated so you will not be able to use the greenpois0n loader to install Cydia.

However, you can install Cydia using redsn0w, by checking the “install cydia” box.

You will then keep your Untethered Jailbreak 😉

~~~~~~~~~~~~

After several months of endless waiting for some, the Chronic Dev Team finally released GreenPois0n. The current version is the RC5 still in beta version therefore.

GreenPois0n is available for MAC only… (Windows and Linux versions are not yet available but should be available soon.)

The official site http://www.greenpois0n.com/ is totally HS due to the many requests sent to the server.

You should know that GreenPois0n is unable to hacktivate your device, so you will need the original sim card of your operator unless you have unlocked officially with your operator and Apple.

For those who wish to unlock you should not update to 4.2.1 but wait, otherwise you risk being blocked for a while…

Very good news, no need for SHSH or anything at all. If you bought your device today you will be able to Jailbreak in 4.2.1 with GreenPois0n 😉

Step 6

The GreenPois0n software confirms you with a Complete button! that the Jailbreak is over, let’s move on to the side of the device.

Once started, a “Loader” application appears on the SpringBoard.

The download will then start …

  • It is likely that the download will not start … you have to quit loader and start again until it works …
  • We also found that the download crashes often, you have to start again until it works.

Be careful not to let the device go to sleep, because the download must be done from scratch !!!

Step 7

Restart the device and you should have Cydia!
