    Default 3GS updgrade/re-jailbreak question
    Hi

    I've tried looking for a straight answer to this...

    I have a 3GS and it's already jailbroken and not unlocked.

    I'm running on

    Version: 3.0 (7A341)
    first five numbers on the serial are 87926
    Modem Firmware: 04.26.08

    Question is this...I want to upgrade to the newest os and jailbreak it. Do I have to reset my current phone back to factory settings, then upgrade through iTunes to iOS 4.1 then RE-jailbreak? Or is it possible to just upgrade to iOS 4.1 through iTunes and then re-jailbreak? ( also, what is the best method of jailbreak currently )

    I don't want to lose any of my apps/contacts/etc but will if necessary to upgrade. I just can't afford to brick my phone by screwing something up.

    Thanks and sorry if this has been asked before. I'd just like a straight answer.

    Update your itunes to the latest.
    Go to iH8sn0w.com and download Snowbreeze 2.0.2 and download 4.1 ipsw
    Run Snowbreeze in Expert mode, uncheck the activate my iphone under General.
    Build your custom firmware of 4.1 from Snowbreeze 2.0.2
    Now put your iphone into Recovery mode
    Do the Shift + Restore to custom firmware of 4.1
    Once restored, put your valid sim to activate
    Now you are jailbroken at 4.1
    Open up Cydia and unlock with Ultrasn0w.
    You are all set.

    yeow if he needs ultrasnow to unlock, then wouldn't he need to set the activate button ON? If he needs an unlock, then he cannot activate after the upgrade.

    Since the OP states he is currently not unlocked then I assume he doesn't need to unlock at 4.1?

    If that's the case, then a regular itunes upgrade to 4.1 will be fine, and then just GP or LR to jailbreak??

    ONLY IF NO UNLOCK REQUIRED!
