How to downgrade back to iOS 5.1.1 without jailbreaking our phones?
I was expecting Siri, as described on the description of the iOS 6 update on my iPhone 4. Didn't get it. Also, I want features that was a part of my iOS 5 experience I don't have now with iOS 6. I want to downgrade back to iOS 5.1.1. I tried to use my old iTunes to restore the old OS, but got an error.
iPhone 4, iOS 6
