CSC or consumer software customization is one of the three main software components on your Samsung Galaxy SII device. First being the PDA or firmware that happens to be most visible part to the user. Second is Phone or Modem/baseband that is responsible for the strictly phone related functionality of the device. Third component is CSC which is mainly used for the carrier branding, APN setting used for data connection, carrier branding, MMS functionality for the specific service provider and other region specific software packages. You can change the CSC of your device if you have multi CSC packages installed.
Keep in mind this will wipe your data on the phone. So don’t attempt this procedure before making a backup! Although, I think SDcard data shouldn’t be effected.
Procedure is very simple to follow and is as follows:
1) Find the IMEI# of your Samsung Galaxy S2 device. Just go in to Setting –> About phone –> Status and look for the IMEI# number and note it down.
2) Type *#272*Device IMEI# in the dial pad of your device.
3) Now select the desired CSC.
4) Your device will automatically reboot afterwards.

Please note that I have tested this one on my international version GT-I9100 of Samsung Galaxy SII with the stock firmware installed. This functionality shouldn’t be related to if your phone is rooted or not. Although I have a rooted SGS2 device with SpeedMod kernel installed.
