Here's a quote from @Planetbeing:
"Yeah, I'm not really sure what all the doom and gloom is about. The fact is, I have an untethered iOS 6.0.2 JB running on my iPhone 5 right now. The reasons it's not released are because 1. releasing it would burn an exploit we want to save for ourselves so we can always get in to look at new firmware and help JB in the future, 2. iOS 6.1 is coming very soon and will likely break a small part of it anyway, there's no point in sacrificing the many bugs it won't break.
Anyway, where there are 4+ bugs (that it took to get this to work), there's gotta be one or two more so while jailbreaking is getting harder, reports of its death are highly exaggerated."
