    I want to JB my sister's 3G and I understand I need Spirit to do it based on this:
    http://www.jailbreakmatrix.com/

    It also says "Do not upgrade if you use an unlock on an iPhone 3G or 3GS. (You can, however, restore to 3.1.2 if you have SHSH blobs for that version.)"

    What does that mean exactly? Does it mean if you use Slide to Unlock? Does it mean if you use a password/PIN after slide to unlock? Does it mean if phone is unlocked?

    Also if she does use the passcode lock on here phone is it ok if she disables it before the JB and can she activate it again after?

    I just feel the words "if you use an unlock on an iPhone 3G" are a bit vague. Any clarification would be greatly appreciated. Her phone is not currently JB.

    Thnak you!

    It means a software carrier unlock like ultrasn0w. Upgrading your firmware before you are sure a new unlock is available if you rely on such an unlock to make your phone work on your non-official carrier can render your phone useless. That information is a bit out of date, however, as the 3G can now be jailbroken and unlocked at 4.0.1; it is still true for the 3GS, which cannot yet be jailbroken on iOS 4.0.1 yet.

    Unlocked in this context means the phone is not locked to ATT as the cellular carrier.

    I've JB quite a few 3G phones and still don't use Spirit. I just use Pwnage or Redsn0w. Go to iclarified.com for all the tutorials.
