Name of network

[Guest MR_E]

I'm looking for a way to change the name of the network I'm on. Vodafone in the Netherlands used to be called Libertel. The phone I used previously with this SIM (R520m) 'learned' the new name during a software upgrade by Ericsson. The same SIM in my SPV only shows the old name. So I assume the network name is stored on the phone.

I have been looking for the location this name is kept, but unsuccessfully, so far - it isn't in the registry, and not in the XML files I've checked sofar.

Can someone point me in the right direction?
