setoperator.bat - is this necessary?

[Alistair George]

In the sun_dream ROM upgrade, I notice this file setoperator.bat which is to do with vodafone or orange. When its run, it cannot find files eg:
I:\>setoperator vodafone

Setting Operator to [vodafone] for ROM

Is this batch file meant to be run after the ROM burn?

This BAT is meant to modify the ROM image you are going to flash (not the flashed one). You don't write operator name as the parameter, but operator ID. For ex. Polish operator Era GSM used T-MOB009 (more examples http://wiki.xda-developers.com/index.php?pagename=BA_Upgrades).
You can read (on clean, original, not yet reflashed device) using another program.
If you are flashing WM5/WM6 there is no need to use this BAT, as CID lock is not checked at all, and moreover: AFAIK if the device was already flashed with ANY rom without setting OP ID, original operator ID is already lost.
