So my gf has an iPhone 4 that is still on iOS 4.3.2 - I've been hesitant about upgrading because everything works well for her and I know some updates cause issues. Also, she really doesn't care about a new iOS as long as everything "just works". Now she's finally running into issues where apps require a newer iOS version. So I want to upgrade to a 5.X version of iOS as I've read many versions of 6 have wifi issues and that's huge for her. Is the only way to do this via jailbreaking? With Pwnage or Redsn0w I guess? I'm on a Mac. What's the best method? Thanks for any assistance.
