SIM-unlock an activated iPhone version 1.0 + modem version 03.12.06_g

[cafri]

I have an activated iPhone version 1.0 (1A543a) and modem version 03.12.06_g

How should I SIM-unlock it?
Should I simply restore to 1.1.1 and then activate + AnySIM?
Should I do something else?


Thanks in advance.

if that is a 1.1.1 or 1.0.2 OTB phone than use this guide

I have the same scenario:
It is not a 1.1.1 nor a 1.0.2 firmware, but a 1.0 firmware that was already jail broken and activated (using iBrickr) and unlocked (using AnySIM, first version I guess).

I want to use 1.1.1 firmware version and unlock it (probably with AnySIM 1.2)

The question is how to achive this?
Most importantly, what is the correct procedure to upgrade to 1.1.1??

After correctly upgrading to this firmware without bricking the iphone, the rest is relatively easy.
Any ideas, comments or suggestions?

Thanks in advance!
