CSC settings define prvider/country for a specific firmware. For example XXJL2 requires CSC with tag "DBT" for Kies to properly recognize it and allow upating. Otherwise you'll just get a "This device version cannot be updated" error in Kies. Changing CSC can also fix certain problems like my problem with received SMS messages where contact names were not shown even though i had them in my phonebook.
Changing CSC will reset the phone back to factory default (same as Master Reset or Hard Reset), meaning ALL data inside phone memory (music, images, contacts, apps) and all settings will be ERASED. Data on memory card will remain. So be careful when changing CSC settings. Backup ALL your data first, even the one on memory card, just to be sure.
By changing CSC you cannot break the phone, but anything is possible i guess. It will still run, just language selection might be a bit off and certain services/functions might not operate correcty. Make sure you remember which was selected by default, so you can set it back if anything goes wrong!
You can open the preconfig directly by typing *#272*[insert actual time here]#
For example when it's 18:35 on the display, then you type in 1835.
It has to look like this: *#272*1835#
After you hit the # sign, CSC selection menu will appear.
Thx for this goes to user "Bence"
How to re-configure CSC:

New input field will open, enter this in it:
You should get a list of CSC's. Here you can select the country/provider.

For some reason there is no "KOR" on the list, the one which is on my Wave, next to DBT which is for Germany.
Maybe this will come in handy for some users. For example, matching firmware with correct CSC will allow you to update firmware through Kies when the Kies says "This device version cannot be updated" and so on. But can also break things as mentioned above.
just try procedure..
