My auto focus stopped working on my iPhone. Went to Apple store today and they replaced it. It has 6.0.2 on it and I wondered if there was any way to upgrade it to 6.1.2 before I JB it. Store wanted to update it to latest so I could restore from my backup, I said NO NO NO leave it alone. Don't mind starting over but have to have JB. I take it there no way to use my backup as it was on a newer iOS version?
