pod2g of the Chronic Dev Team just teased an untethered iOS 4.2.1 Jailbreak for iPhone (and we presume iPod touch and iPad) on Twitter:
< I really don't know what's funny about this. You do ?
The video shows an iPhone 4 running iOS 4.2.1 in all its untethered glory. Apparently this might be coming soon in greenpois0n update though whether or not they'll use it now or save it for when Apple releases iOS 4.3 is unknown. (If they use it now, Apple could patch it in iOS 4.3 and they'll have to come up with yet another Jailbreak).
What do you say, you want iOS 4.2.1 untethered now, now, now or would you prefer them to play it safe so you can quickly untether iOS 4.3 in February or March? Video after the break!
