Chronic Dev Team and iPhone Dev Team have updated the greenpois0n tool for a successful untethered A5 jailbreak of the iOS 5.0/5.0.1 running iPad 2 and iPhone 4S.

The solution is reportedly called corona jailbreak, due to the use of pod2g corona exploit, and has been really hard to concoct. We did catch a glimpse of an iPhone 4S with an untethered jailbreak a couple of days ago and were expecting to finally see the solution in real life.
