S40 Network Name <-> ID

After flashing my S40 to vers 9.0.0, and resetting the phone to get rid of a few adressbookitems that should't be there, my phone tells met the network code of the operator, instead of the network name.
I already found out that this info is stored in the eprom, and i think the reset did a bit too much.:confused:

an anybody give some advice to restore the names???

Thanks....
