    Default Upgrading iPhone4 from 4.1 to 4.3.2

    Hi guys,

    I need your advice to make an upgrade to my iPhone.

    When I bought it, it came with iOS 4.1. Since then it's only been jailbroken.

    Now I want to upgrade it to the latest firmware that can be jailbroken, but also I would like to remain with the 2.10.04 baseband, so if an unlock is released I have a better chance with the old bb. Can this be done? Can I upgrade to 4.3.x and remain with the old bb?

    If it's possible, I would really appreciate if you can tell me how to do it.

    Thanks in advance,

    El Miye

    There's no clear information as to whether staying with 2.10.04 baseband will be of benefit for a future ultrasn0w style unlock or not.

    My guess is - yes - because Apple does proactively close exploits if they are identified.

    However 4.3.x works poorly with older basebands... You get incorrect signal strength display.

    Topanswer your question, yes you can update or restore to 4.3.x and retain your old bb (via correctly made Pwnagetool or sn0wbreeze custom IPSW. You can also use TinyUmbrella to block the baseband update, but then your restore/update will fail near the end and you will need to use another tool, to exit the recovery loop)

    Hmmm, I'm gonna try to create a custom IPSW with the new sn0wbreeze... If I have any issues, I'll update the baseband with a normal restore and ditch the old one. For now I don't need the unlock, but I always wanted to have the choice in case I needed it... Guess someday there'll be a unlock for all FW, something like the IMEI unlock that somebody was selling some weeks ago.

    Thanks for your advice Olethros!
