GreenPois0n RC5 Untethered 4.2.1 Jailbreak Supports iPhone 4, 3GS, iPad, iPod touch 2

The news today is that it appears GreenPois0n RC5 will be bringing untethered jailbreak to iOS 4.2.1 sooner rather than later. Twitter user @JHackstar tipped us off to a Wiki showing that GreenPois0n RC5 is ‘coming VERY soon’ and will support all devices.

The reason for the new movement is that Apple has now closed the loophole hackers have been using up until iOS 4.3. Now there’s obviously no point in waiting for the new update to be released it’s been decided that GreenPois0n will go ahead as-is, with a new attempt at 4.3 to be made later. iPhone hacker Pod2g has also confirmed this on Twitter:
The good point is that because of this (and the fact that Apple fixed the kernel exploit in 4.3), we’re all working back on releasing gp.
That’s great news on 3 levels. First, I’m sure plenty of you have been waiting for an untethered jailbreak on 4.2.1 for a long time now.
Second, the new GreenPois0n will work on ALL hardware. It’s great to hear that nobody will be left out in the cold this time around.
Thirdly, it’s good to hear a release isn’t too far away.
More info coming as soon as we get it, so stay tunes folks!
