Please peeps I desperately need some help. Since installing the newest update, my 4s is basically useless. Facebook barely works, Twitter won't load at all; and now my email (Outlook) is screwed. With FB, the phone FREEZES so that I can't even turn it off or close the app. Watching videos is impossible. With email, I cannot open them or delete. Apple keeps telling us that 8.2 has fixed "all problems" for the 6 & 6+. What about the earlier models?
