On January 28th, a mere five days from now, iOS 6.1 beta 4 will expire. If the past is any indication, then Apple will act, either releasing a 5th beta for iOS 6.1, or releasing the iOS 6.1 golden master — a final baked version, which shortly precedes a public release.
Since the firmware expires on the 28th, then I don’t see Apple waiting until that day before making a move. The most realistic time period for it to drop a new release — whether it be beta 5 or the golden master — would be tomorrow, the 24th, or Friday, the 25th.
The reason why the timing is so interesting for us, is because we believe that the hackers working on the iOS 6 jailbreak are waiting for a final version iOS 6.1 to be released, before finishing up and releasing the long awaited jailbreak.
Pod2g has chimed in to a series of tweets from jailbreak developers that suggests a publicly releasable jailbreak has been found but is just waiting for the release of iOS 6.1.
We hve just reported that planetbeing had said, "Tons of progress the last few days. I think the future is looking bright for jailbreaking. :)"
And now pod2g added, "Come on Apple. Release that 6.1 now! /cc @planetbeing @pimskeks @MuscleNerd"
This is the strongest evidence yet that the devs have found a jailbreak that can now be released to the public but are still waiting for the release of iOS 6.1 so as not to burn an exploit. There would be no point in releasing a jailbreak at this time for a firmware version that will be updated in just a few days.
