Thread: Updating from 3.1.2 to 4.0.1

    Default Updating from 3.1.2 to 4.0.1
    I see that 4.0.1 can be unlocked, so I'm thinking about trying to upgrade from 3.1.2 since there are some games that won't work. However, when I try, the Apple verification rejects me. Is there anyway to upgrade?

    Do you have your shsh's saved for 4.0.1? Use tiny umbrella to find out.

    Can you open up Cydia and look at the front page in green letters and tell me what you see?

    There you go, you have all the shsh blogs.
    Give me the first 5 serial numbers starting from the left before I proceed.

    Nevemind, do this :
    Pc : Run Notepad as Admin and open up to your hosts file:
    Cwindows\system32\Drivers\etc\hosts and add this line to the bottom,
    74.208.10.249 gs.apple.com
    and mark the rest infront with this # to ignore
    save it and reboots your pc
    Put your iphone into recovery mode
    Do the Shift + Restore to stock 4.0.1 ipsw
    Once restored, put your official sim to activate
    Jailbreakme 2.0 from Safari on your Iphone
    Slide to Jailbreak.
    Unlock with Ultrasn0w.
    That is it.
