Still holding onto my 5.1.1 JB until this vaporware hit's the streets.
I wonder if this is (parcially) why Apple is dragging out 6.1. To let the JB community twist in the breeze.
I doubt it. 5.1's final beta dragged on for WEEKS until the Spring when the new iPad's were released. The release is either imminent (6.1) or they're holding off for an iPad release in the Spring, like every prior year. I sincerely don't think Apple holds off on iOS releases for weeks at a time to combat jailbreaking. If they REALLY wanted to crush an exploit, they just have to release 6.1.1.
