Untethered redsn0w Jailbreak for iOS iPhones, iPods and iPads Coming Soon... How Soon?

New redsn0w untethered jailbreak for iOS 4.2.1
iPhones, iPods and iPads coming out by
Christmas 2010?

Yes! According to MuscleNerd of the Dev-Team, the untethered  redsn0w jailbreak,
for devices running the new iOS 4.2.1, is about ready. The newest version of redsn0w
will not only jailbreak iOS 4.2.1 devices already tether-jailbroken users can use this
new redsn0w to re-jailbreak to get untethered support without a full restore. So all of
your Cydia apps and other tweaks will not be removed.

MuscleNerd:

"Got 'backup plan' for untethered 4.2.1 JB working (video coming up). Uses mysterious 4.2b3 hashes Cydia kept for you
(It’s a "backup plan" because comex is working on a more extensible one, but this method is also generalizable)
ipt4g 4.2.1 untethered JB w/4.2b3 kernel: http://is.gd/inE4e … Wastes no exploits, but upcoming @comex JB maybe better."
