    Restore to custom firmware of 4.1 created by snowbreeze 2.1`
    You will need the official 3g 4.1 ipsw when you build your snowbreeze firmware. Use Expert mode, check the activate part if you need hactivation. If you run into errors, you can run ireb 4.1 RC2 first to bypass the error by putting you into DFU mode and then shift + restore to Snowbreeze_4.1.ipsw

    Make sure you have itunes 10.1

    Unlock again with Ultrasn0w from Cydia.

    No you will restore to a custom 4.1 made with sn0wbreeze, otherwise you will lose the ability to unlock. Here is a step by step if you need it: HOW TO: Jailbreak iOS 4.1 with Sn0wbreeze 2.1
