Thread: Upgrading/Jailbreak/Unlock iphone from 2.1 to 3.1.3

    Default Upgrading/Jailbreak/Unlock iphone from 2.1 to 3.1.3
    Hi Guys,

    Need some help over iphone, i m not much into it so seeking some guidance.

    My query is:

    I have iphone 2g, 8G.
    The current OS : 2.1 (5F136)
    Model : MA712LL
    Modem Firmware : 04.05.04_G

    I want to upgrade this to 3.1.3 (latest) for this model.

    I had referred one post on this forum and it pointed to the below link:
    iClarified - iPhone - How to Unlock/Jailbreak Your iPhone 2G on OS 3.1.3 Using RedSn0w (Windows)

    My doubt is:
    1) The procedure describes the jailbreak/unlock from 3.1.2 and not 2.1
    2) Do I need to first upgrade from 2.1 to 3.1.2 and then jailbreak/unlock
    3) Is redsnow a good software for the same?

    Please advise!

    Thanks
    Sameer

    Use PwnageTool to create a custom firmware to update your iPhone while preserving your baseband and keeping your unlock. Use ultrasn0w to unlock then.
    Until the next time… And if I help you out, give me a "Thanks!" Thanks!

    No, you don't have to do 3.1.2, just hit restore in iTunes to take you to 3.1.3 and jailbreak with redsnow 0.9.4 but browse to stock 3.1.2 , BL 3.9 & 4.6 to unlock.
