The hacking community has been waiting patiently for the latest jailbreak. Looks like its coming sooner than later. A video posted by p0sixninja on YouTube shows off the untethered jailbreak for 4.2.1. I personally think that the exploit should be saved for 4.3 as it will be released close to the launch of the iPhone 4 on Verizon. Note: If this jailbreak is released your Cydia store/jailbreak apps will need to be updated. That being said, if you rely on MyWi, 3G Unrestrictor, LockInfo, and so on, it might want to wait for some compatibility updates before moving on.
