    Hi All.

    I searched all over and couldn't find the answer. I had a 16GB 3GS with 3.1.2, 5.11.07 modem firmware and latest iboot (tethered jailbreak, also registered on saurik's server). I sold the iphone after a restore to stock 3.1.2 on ebay to a guy a month ago. Now he opened a conflict with paypal - he can't jb/unlock. I'm trying to help him out.

    He's outside the country and I didn't give him my AT&T sim card. My questions:

    1) Do you need an AT&T sim card to jb/unlock an AT&T phone?
    2) Do you have to be on AT&T's network?

    Thanks in advance.

    PS: I had successfully used blackra1n/blacksn0w previously to get a tethered jailbreak/unlock and i'm aware of the 3.1.3 apple firmware, if that's what you're thinking. :)

    You already know the answers to these questions because you claim you jailbroke and unlocked it yourself.

    A 3GS on firmware 3.1.2 can be JB with Pwnage Tool, Redsn0w or Blackra1n.
    It can be unlocked with Ultrasn0w or Blacksn0w depending on the baseband.

    No AT&T account or sim is needed.

    Thanks.

    BTW, I didn't know the answers because I had my AT&T SIM in the US and activated and used the phone on AT&T before JB/Unlocking it, and I had read on iClarified that:

    "The BlackRa1n jailbreak will work with the latest 3.1.2 firmware; however, it will not hacktivate your iPhone. This means that if you are not on an official Apple approved carrier BlackRa1n cannot activate it."

    As far as I know, Blackra1n RC3 does hacktivate an iPhone. Otherwise none of the thousands of persons who has JB with Blackra1n then unlocked with Blacksn0w could use their phone.
