How to install Anysim 1.2 ?

Hi, I have an unjailed 1.1.2, ATT SIM card and activated through Mac iTunes 7.5. I am running the 04.02.13_G Modem Firmware. I go to Europe soon and want to use it over there with my Swiss SIM card.

I updated to 1.1.2 that was unlocked at 1.1.1 with Anysim 1.1. I did the OktoPrep and upgraded. It is now jailbroken and works great on ATT. But I want to unlock it again. AnySim is not through the iphone Installer yet so I downloaded the file and now what??? In the "read me" it sais: 2. This version works only with 4.02.13_G baseband version and can be run on 1.0.2, 1.1.1 or 1.1.2 jailbroken systems.

So I don't have to download it to 1.1.1 and install it? How do I install it. I pressed anySIM and in Terminal it sais: Bad CPU type in executable.

I don't have OpenSS installed. Do I need this and than what. Even if I download how do I install it?

Thanks for any help.

No need to go back to 1.1.1 do this while your on 1.1.2

on installer app go to system and install BSD subsystem
on installer app go to sources and add rep.frenchiphone.com
go to install and select frenchiphone and install anysim 1.2.1u
go to settings and turn on airplane mode
unlock with anysim
restart phone
your unlocked
