    Hello everyone,

    Trying to unlock this 3GS phone.

    Modem Firmware: 05.16.02
    OS: 4.3.5 8L1
    Model: MB716LL
    Serial number: 88932LE43NQ (2009, week 32)

    I understand I need to update to 6.15.00 and will lose GPS, that's fine with me.

    I don't have any SHSH blobs.

    Do I have the steps right so far?

    Downgrade to 4.1
    I have this file: iPhone2,1_4.1_8B117_Restore.ipsw
    (how do I actually do this? Seems like I need an older version of iTunes and maybe some SHSH files?)

    Use Redsn0w to Jailbreak.
    Use Redsn0w to install iPad Baseband 06.15.00.

    Run Ultrasn0w in Cydia to unlock.

    Is there a better way to this?

    Thanks for any advice!

    I don't know for sure if Apple is still signing downgrades to 4.1, so in the case that they are not, your only option would be to update to iOS 5.0.1 and update your baseband on that version.
