Sn0wbreeze 3.1.3 is now available for download which can jailbreak iPhone 2G, 3G and iPhone 3GS (old bootrom only) on iPhone OS 3.1.3.
Ultrasn0w unlock is for iPhones with baseband 04.26.08 baseband. If you are on 05.11.07 baseband, then you may use Geohot’s blacksn0w unlock which was released last year with blackra1n.

Step 1: Follow the guide posted here to jailbreak your iPhone 3G or 3GS using Sn0wbreeze 3.1.3 on iPhone firmware 3.1.3.

*Start “Cydia” on your iPhone.

  1. SOONER,

    How do I know if Im on old Bootrom? Or on which baseband?

  2. Isis,

    Go to Settings, About.

  3. SOONER,

    Ok, let me see if I have this correctly. I am on a JB 3.1.2 basband 5.11.07.

    So if I upgrade my workin functioning device to 3.1.3 I then can turn around and unlock with the same Blacksnow from Geohots that I have JB from in the first place?
    And then just use PKGBackup to restore all my beloved items.

    If so thats a breeze, but I also say if its not broke, dont fix it!!!

    Thanks for the replys

  4. Tristan,

    There are no new features on the new 3.1.3 firmware. No need, no use to upgrade. The only thing Apple made is to patch the holes GeoHot and DevTeam used to jailbreack 3.1.2.
    The real updates will be in 3.2 or 4.0 .W8 t-ill then.
