    You can update to 4.0 and jailbreak and use ultrasn0w. All you need is a AT&T sim to get passed the connect to iTunes first then you download ultrasn0w and you have hactivated it.

    Please correct me if I am wrong

    Ya you do because Jailbreak me is not a hacktivate you have to restore jailbreak put sim in ( to get around connect to iTunes)then install ultrasn0w that is to be released in the next day or 2

    EDIT: Well I was guessing that the phone was us AT&T but if the iPhone's default network for you country is something else use that type of sim if it was not factory unlock.
