Those at 7.x waiting for JB, maybe treat 7.0.4 as exercise in restraint. Won’t affect JB if you slip up, but test your ability to avoid it!
…but for those enjoying the 6.x JB, avoid 7.0.4 . There’s no going back (always worth saying that for sake of JB newbies)
The last update we received about the possibility of iOS 7 jailbreak was in early October when Planetbeing tweeted, "We're still working hard on the jailbreak. May have all the pieces at this point (but not certain yet)."
The bootrom exploit can devices permanently vulnerable to a tethered jailbreak regardless of iOS version. The last bootrom exploit was limera1n found by Geohot which supported A4 devices like iPhone 4 and below.
Available for: iPhone 3GS and later, iPod touch (4th generation) and later, iPad 2 and later
Impact: A local user may be able to execute unsigned code

Apple has released iOS 6.1.1 beta to developers. It’s only been a week since Apple released iOS 6.1 to the public. And it's just 48 hours after the iOS 6.x evasi0n jailbreak was released. Release notes indicate maps improvement and some other optimization. well, we understand that the main purpose of iOS 6.1.1 is probably to fix vulnerabilities used by envasi0n jailbreak.
Pod2g confirmed that the Evad3rs Dev-Team is ready with a jailbreak for iOS 6.1 and credits Planetbeing and Pimskeks for the accomplishment in an interview with iDigitalTimes.
"For your information and this is important to me that everybody knows about it also, this jailbreak will be @planetbeing and @pimskeks. I arrived at the end, gave ideas that pushed them to their maximum, I kinda unblocked the situation, but it would certainly have happened without me helping."
Last month, chpwn revealed that his jailbreak would be reserved as a failbreak. That means it will be limited to jailbreak developers and won't be released to the public. This is being done to make it easier to discover new exploits (which will be used for public release) in the future.

Last month, chpwn revealed that his jailbreak for the iPhone 5 would be reserved as a failbreak. That means it will be limited to jailbreak developers and won't be released to the public. This is being done to make it easier to discover new exploits (which will be used for public release) in the future.
