Just out of curiosity, how many of you have gone back to 6.1.3/4 after trying b3? I downgraded my iPad 3 (kids' games didn't work) but I've been trying to be patient with my iPhone 5 (daily driver) ... I have lockups every other day or so, plus a handful of other bugs - I'm seriously considering going back to something more stable if they don't release b4 in the next day or two.
Anyone else? Have you stuck with it or gone back?
