Just to clear up a couple things:
1. Sunday was an ETA; evad3rs never stated a definite release time or date.
2. This jailbreak does work on 6.1. Therefore, there are no good reasons to stay on outdated firmware.
planetbeing addressed all the people pushing to just hurry up and release the JB on reddit, and brought up a very valid point: If a JB gets released with minimal beta testing and wreaks havoc on devices because it's buggy, it just gives jailbreaking an even worse public image than it already does...do that a couple of times, and the DMCA might just get changed to make jailbreaking illegal just like unlocking did.
Be patient, y'all. I'd rather wait another day or two than have a buggy jailbreak...
