    Jailbreak easily at jailbreakme.com
    Then unlock by installing repo666.ultrasn0w.com in Cydia
    You can find it under manage/sources

    thank you.
    Run redsn0w 0.9.9b7 to jailbreak, run it again to install ipad bb to unlock with Ultrasn0w but it breaks your GPS function.

    You cannot restore to 4.2.1 unless you have the blob saved but you can resstore to 4.1 , jailbreak with redsn0w 0.9.6b8 or Limera1n.
    Run redsn0w 0.9.6b8 again to install ipad bb to unlock with ultrasn0w.

    tried to restore it to 4.1 from itunes and I keep getting the 1394 error. Do I need to download tinyUmbrella and try to restore it from there?

    Point your hosts file back to apple server for 4.1 restore by running tu , adv and uncheck : set hosts file to cydia , close it and restore to 4.1

    You should have gotten one that already has been unlocked rather than risking to unlock with ipad bb.

    yup should have done that in the first place. thanks for your help though..
    So if a phone is bricked means even in the future like 6 months or so, it cannot be unlocked or usable at all?

    If No imei or No baseband, it is permanently bricked. Are you still looking for a 3gs and unlocked ?
