X-Gold 608 Unlock

This is only possible for the 2G iPhone

Currently, the 3G (software) unlock is the biggest missing piece of the iPhone community. It is more difficult than the previous unlocks due to the fact that the baseband bootloader is sig checked.

Possible Methods

Class 1

• Find an exploit in the bootrom to break the chain of trust
• 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 hack such as the TurboSIM Unlock
• Find a way to patch running memory to "unlock" the phone on every bootup
