how to upgrade to 4.01 3GS

    trying to upgrade, iphone 3GS, 3.13, but i cant restore to 4.01, in itunes

    how can i get round this? as the latest version now is 4.02


    Download the firmware from here

    Save it to your desktop.

    In itunes, hold shift key and click restore. You can then choose which firmware to use (i.e the one you saved to your desktop).


    No its not possible because apple do not sign the 4.01 firmware anymore due to the pdf jailbreak,

    I tried downloading but no joy


    Sorry unless you have SHSH blobs saved from a previous jailbreak then you just have to wait for the iphonedevteam to jailbreak the 4.02!
