    i bricked my iphone 3gs 32gb, updated with itunes to 4.0.2 and it updated the firmware too.

    i down graded to 4.0.1 and jailbroke with jailbreakme.com and everything works just fine.

    try that?

    If your Cydia says it has the SHSH files for 4.0/4.0.1 feel free to download tiny umbrealla, fun it, restore to the firmware and jailbreak with jailbreakme.com

    since you rely on an unlock you will need an official carrier sim to activate the phone before you can jailbreak with jailbreakme
