Until recenlty, the 3G software unlock was the biggest missing piece of the iPhone community. It proved more difficult than the previous unlocks due to the fact that the baseband bootloader is signature checked by the bootrom. The dev team has successfully unlocked the current latest baseband version, by overriding carrier locks on-the-fly in RAM, therefore at boot the baseband bootrom can validate the bootloader, and the bootloader can validate the baseband. The unlock, code-name ultrasn0w, was released to the public on 23 June 2009 for baseband 04.26.08 only [1].
Possible Methods
Class 1
- Find an exploit in the bootrom to break the chain of trust. The Dev-Team successfully dumped the bootrom, but they won't release it as it's copyrighted code.
- Improve by several orders of magnitude the NCK brute forcer, and find a way to extract the CHIPID and NORID
- Find the theorized algorithm of NCK generation
Class 2
- Use a SIM hacks such as the TurboSIM Unlock
- Find a way to patch running memory to "unlock" the phone on every bootup. This is how ultrasn0w works.
- Find an exploit in the Baseband Bootloader so you can downgrade the baseband, then use ultrasn0w. Geohot and the iPhone Dev Team found (independently) an exploit in bootloader 5.8, but it isn't useful enough as only very-early (week<30) iPhone 3G units have bootloader 5.8.
