GreenPois0n for iOS 4.2.1 is out — Chronic Dev Team released GreenPois0n for iOS 4.1 back in October — for all of you out there who want to jailbreak your iPhones and this time it’s untethered.
You heard well, it’s untethered, meaning that you will no longer have to jailbreak your smartphones again and again after every reboot. Untethered jailbreak for iOS 4.2.1 was expected around Christmas last year but it’s finally here, even though a bit late, but better than never! You can grab it by following the source link, and only the Mac version is available as of now, but be warned that neither we nor Engadget who first reported it were able to test the jailbreak. It’s also worth mentioning that the source website is currently down or sluggish at best, which can mean a lot of things.
