My trusty old 4th gen finally died from water damage today. I never updated to iOS 6 so I had that original YouTube app that was amazing. I believe I had updated it to iOS 5 though but I don't remember. Anyway I am thinking of buying a used 4th gen online and wanted to know..... Is it possible for me to get back to using that iOS if I order another 4th gen? I really miss it already. I used it for watching YouTube and surfing gamefaqs when I was tired of my iPad.
