    I have a 3gs with the newer bootrom currently on 3.1.2 that I jailbroke using Blackra1n. I am a windows user (obviously). I would like to upgrade to 4.x.

    I tried following the instructions here:
    Jailbreak iOS 4 on iPhone 3GS New bootrom with SnOwbreeze (Snowbreeze) v 1.7 [How to]

    But it's the download links dont work for LibUSB for iRecovery and frankly I don't know if that's even really necessary. Also given that the post is almost a month old, it could very well be out of date.

    I'm also wondering if I should uninstall some of the Cydia apps first such as the one that creates folders (since ios4 has it built in) or if there are any other apps I should uninstall as well first?

    Can someone please point me to a current walkthru to get my phone to 4.x? Much appreciated. Thanks.

    I don't have a walkthough but Tinyumbrella is very good for kicking your phone outta recovery

    Thanks, but no issues atm. I just wanted to make sure to have what I needed and was current before heading down this path. I'm an old school windows mobile guy, used to cooking my own roms and such, but the iphone is a relatively unknown platform and OS for me once I venture outside the well documented jailbreak paths

    Found a 3gs ios4 ipsw that had been generated by sn0wbreeze already, but itunes gave me a failure to restore error unfortunately.

    I'm running itunes When I originally jailbroke, it was recommended not to update itunes, so I have not in a very long time.

    I don't think iOS4 works with anything under 9.2, also if you have categories or any custom icons reset them all to standard before you jailbreak

    Already wiped out categories. OK, upgrading itunes to 9.2 and will try a restore.

    No love. The iphone could not be restored. An unknown error has occurred (1602).

    been following this one:
    iH8sn0w's Forums • View topic - Pwning 4.0 on 3GS (New Bootrom) | ipt2g MC | ipt3 w/3.1.2

    but i'm stuck on running ibooty, i never get the logo on my phone but seems tons have had this problem.... no solution yet, been working on this for hours. my wife is ready to evict me.

    Done. I'm now running ios4. Now I just need to figure out the easiest way to restore all my istore apps, cydia apps, rock apps and contacts.... and oops... I wiped all my photos I guess. Duh.
