The Greenpois0n jailbreak tool has been updated and is now capable of jailbreaking iOS 4.2.1 devices untethered. The latest version released at last night. and it’s download is now available.
The Mac version will do an untethered jailbreak for iOS 4.2.1 this time. there is no new upadte for the Windows and Linux versions, so if you need untethered, you’ll need to find someone with a Mac at the moment.
iOS 4.2.1 untethered jailbreak was released earlier than expected is due to Apple closing the hole on iOS 4.3 beta which means this method wouldn’t have worked anyway this is the main resion of lauching it.
Users can get the update now over at Greenpois0n. One thing to note is that it was pushed out quite quick, so it might be worth waiting a day or so to make sure it’s stable and wont cause any problems for you.
