@geekmaster: There's (some) mixed reports right now, but I *do* think Yifan's jailbreak handles the update correctly
(we're essentially doing the same thing at the level the update affect).
That said, we'll know more about the few snafus that popped up after a look at the logs
. But those kind of issues usually come from people using outdated install/uninstall files, and/or doing factory resets thinking it will magically fix everything (which, in some hacks' case, it doesn't, it usually makes more of a confusing mess ^^).
