Thread: Help with Iphone 3gs 3.1

    Angry Help with Iphone 3gs 3.1
    Hello I recently purchased an Iphone 3gs 3.1 from a person on craigslist. I was wondering what would be the best way if possible to upgrade the fw and to jailbreak and unlock it. The phone modem firmware is 5.11.07. I am using a windows laptop btw. Thanks for the help.

    A 3GS requires SHSH blobs to load anything. Use TinyUmbrella to retrieve older blobs (if any) - the current version is available directly from Apple.

    Then use Snowbreeze to create a custom firmware for the version you want, iTunes shift/click restore that custom firmware. Baseband/modem firmware is preserved. Ultrasnow for an unlock.

    The latest 4.3.3 (with a custom firmware) is jailbreakable and unlockable.

    Many guides on MMI and iClarified are much more helpful.

    I am very new to all this. Can you kindly point me in the direction of how I would upgrade to 4.3.3 and then jailbreak and unlock it? Thank you for your help.

    Do you have a Mac or PC ?

    Update your itunes to the latest.
    Create a custom firmware ( cfw ) of 4.3.3 either from Snowbreeze 2.7.3 or Pwnage tools 4.3.3
    Put your iphone into pwned dfu mode either by Redsn0w RC16 , SB or PT.
    Run itunes : shift + restore to cfw of 4.3.3

    No you shouldn't. You should use a custom firmware and preserve the baseband you have right now.

    After your restore to cfw, you are already jailbroken and you have preserved your unlockable baseband, update cydia, and install ultrasnow to unlock.

    Thank you so much guys, I have successfully done it thanks to the help of you two. I just have one more question if you don't mind me asking. I heard there was an error with mms messaging on the tmobile iPhones. Is there a fix for this?

    Don't think there is any issue with MMS at 4.3.3 for T-mobile.
