Title says it all. My wife has my old 4 that's jb on 4.3.3 and has no problems other than the proximity sensor being ******. I want to upgrade to 5.whatever on it once there's a jailbreak but we obviously already missed the 5.0 window. On my 4s, I've put off upgrading to 5.01 as it will obviously be easier for jb whenever it happens if its on 5. But it seems like we may end up getting screwed with hers if we don't go ahead and bite the bullet and go to 5.01 now. I wanna say we're ok and that apple will just release a new version within a few days of the jailbreak that patches that exploit but I'm not sure. Thoughts?
