Mac & Windows versions are currently available:

Like the past GreenPois0n RC releases, RC6.1 includes support to jailbreaking iOS 4.2.1 on the following hardware:

  • iPod Touch 2G, 3G, 4G
  • iPad
  • iPhone 3GS
  • iPhone 4
  • Verizon iPhone 4 (iOS 4.2.6)
  • Apple TV 2

Using RC6.1 is the same as past GreenPois0n RC releases, you can follow our how to guide on jailbreaking iOS 4.2.1 untethered with GreenPois0n or you can use iPad specific instructions.

If you require unlock and baseband preservation, you should use PwnageTool 4.2 instead.

    I tried RC6 and RC6.1 for apple TV 2g running IOS 4.2.1 and the “JailBreak Complete!” box has been grey out for a long time. What is happening? I tried the same step several times and got the same result each time and I have to press “Quit” button to start over.

    my iPad’s home screen now has 2-second lags every each animation after jailbreaking with GP RC6.1.

    is anyone face similar probs?

    half the media is still reporting that iBooks is blocked, they’re so clueless

    btw you can apply this over existing greenpoison jailbreaks just fine
