Just checked my /system/csc folder and the contents are as follows:

contents.db
customer.xml
feature.xml
isnew_csc.txt
others.xml
sales_code.dat

I've confirmed my CSC via SGS Toolbox as being I9000VNZJP3, so it looks fine.  I've browsed the above files, and customer.xml to have the most relevant settings:
