[Prediction/Opinion] Upcoming firmware release.
Hope I'm wrong, but here's my prediction.
New iPhone firmware will be released next week, BUT...
It won't be 1.1.3
Apple will have changed it just enough to render any use of the "leaked" 1.1.3 useless for unlocking.
Apple knows exactly what they are doing, they leaked it themselves to encourage hackers to find the problems.
That way they can fix them before releasing, and not have to pay out of their own pocket for it.
Why devote precious engineering/developers to the task, the hacker community does it for free...
