Well.... if you select "use only 3g" it will use only 3g, and if its not selected.. it will use the one that's available 3g or 2g, or is it that you want "only 2g" option ?
Try editing the system\etc\customization\settings\com\android\phone\custom_settings.xml
<?xml version="1.0" encoding="utf-8"?>
<settings version="807">
<setting key="national_data_roaming_visibility" runtime="false">true</setting>
<setting key="national_data_roaming_setting" runtime="false">2</setting>
<setting key="national_data_roaming_warning_enabled" runtime="false">false</setting>
<setting key="use-3g-only" runtime="false">true</setting>
<setting key="preferred-network-mode-visibility" runtime="false">false</setting>
<setting key="prefer-2g-visibility" runtime="false">false</setting>
</settings>

If you delete the lines in red, and reset your phone.. then you will get an option to choose

I edited it with ES File Explorer too.. but without any problem or error.
You can copy it with ES File Explorer to your sd-card, and then edit it on your pc with notepad++ and then get it back where it belongs on your phone.
OR... copy it(custom_settings.xml) on your sd card, just to have backup (not you will not need it ) and then delete the custom_settings.xml in etc/customization... /phone.
Don't be afraid to delete it

No need of editing and all that just dial *#*#4636#*#* and select phone information

@bitse
If you aren't rooted...
1. If you want to stay on 6.1.1.B.1.100 you have to root, and do what i said to get what you want
2. Or... flash ICS 6.1.1.B.1.54 and then you will get what you want without rooting

Is what doing when what flashing and excluding... what?
Ok just kidding , i think i got your point
The settings that we are talking about are not in the kernel or baseband, so excluding those will do nothing to the "network mode selection".
Why dont you just ROOT YOUR PHONE ?

Read about this tool for backup without root, there are other one's too probably.
If you don't want to root.. just flash the b.1.54 firmware, and you will have the option to change 2g/3g without rooting.
