Just in time for Apple to patch iOS 7.1 ahead of its release. What a waste (unless it's been already patched in 7.1 beta and this is the last chance for this to be used by someone).
I suppose that means 7.1 won't be released until they've fixed it. It's so unimaginably stupid that they didn't wait until 7.1 was released so that the general public could get the bug fixes and performance improvements in that release and a jailbreak as well.
