just follow it step by step, amnesia's guide is very clear...all you need to do is be very patient.

(or else you will brick...)

(don't skip a thing even a single one.) ok?

** and about the QR500 charge, this is UNREASONABLE for version 1.1.1 and below - unlocking. (some shops charge like this..)

** But if its for version 1.1.2 for now, maybe its okay because it includes two choices with different method:

1. HARDWARE UNLOCK (includes opening iphone and this one is very delicate so really you need to pay for the time consumed and hardwork..) - actually, i have a friend who can unlock your 1.1.2 by hardware method, and this is very REASONABLE because the cost is for the "chip" imported and some technical stuff, and i assure that this works perfectly.)

2. TURBOSIM..well you know this already so i don't want to elaborate it. :)
