    Default Can I unlock my 3G yet on 4.1?
    Simple question, I can't understand the stuff on the dev team site.

    I'm currently running 4.0.1 (8A306) with firmware 05.13.04

    Yes, you can use jailbreakme.com from Safari on your iphone to jailbreak and install Ultrasn0w from Cydia to unlock at 4.0.1.

    You cannot yet unlocked at 4.1 baseband, but you could use Pwnage tools 4.1 or Snowbreeze 2.0.2 to get you to 4.1 while preserving your baseband to unlock with ultrasn0w.

    Restore to custom firmware created by snowbreeze 2.0.2, run ireb 4.1 first and then shift + restore to snowbreeze_4.1.ipsw created by snowbreeze 2.0.2 on your desktop. Do not restore to stock 4.1 & you be screwed.

    If you have the official sim to activate, unchecked activate my iPhone in Expert mode under general. Once restored, put the valid sim in and you are already jailbroken at 4.1.

    Unlock with ultrasn0w again

    yeow202 - do you have a tutorial to link to on two posts above on how to create custom firmware with Snowbreeze, etc. I am in the Original poster's boat and would like to get to 4.1 and unlock while preserving my baseband.
