I accidently updated my iPhone 3G S 32gb to 3.1.3
I do not need unlock.
All I need is jailbreak.
My phone is produced in 2009, 36th week.
I just bought the phone from my friend. I'm not sure if he has saved shsh?
When I open Umbrella, and enter the details then click the Sumbit button, it downloads a file. I've tried this from both servers apple and saurik and it works for both.
So, is my shsh saved? Can I go for a downgrade?
