It looks like someone else is getting into the untethered jailbreak fun for iOS 4.2.1. That’s right, today Chronic Dev Team unveiled a teaser video showcasing their untethered jailbreak for the iPhone.
Chronic Dev, the creators of the popular GreenPoison jailbreak tool, are the same devs behind this upcoming tool for iOS 4.2.1, but they aren’t alone in the rush to untether Apple’s latest public firmware.
