    Whatever you do don't use SnowBreeze.

    To get to 4.1 you'll need to have the SHSH saved. Also, a custom firmware.

    1.59 bb

    I'm on 4.2.1 with the 1.59 baseband. I'm not sure if you just don't want to go to 4.2.1 or not. I just used TinyUmbrella and Greenpoison. 4.2.1 jailbreak works good no problems here. Also if you use PkgBackup it will even save all your jailbreak settings and folders. Easiest jailbreak and setup I have ever done. Well not easiest jailbreak, jailbreakme.com was easiest but the setup after was done with a sync and PkgBackup.

    If you don't have SHSH for 4.1, you have to go to a locked bb and 4.2.1.
