Last night, with two members from "FrenchiPhone" forum, we have SIM-unlocked successfully an iPhone 8GB model following the step-by-step tutorial published by Georges Hotz.Waiting for a software-based unlocking procedure becomes available, this procedure is the only one available in Europe to be able to use an iPhone.

This is indeed an extremely challenging operation, as tracks are really thin, and to be successful you need good tools (extremely think wires, 0.2 soldering pin, and good enlarging optical device) and a bit of luck.
