Old mobile operator names

[kosmocos]

My phone displays the old operator names, the ones that were 1 or 2 years ago (connex instead of vodafone and cosmorom instead of cosmote).
For WM5 i saw the registry hack "hklm\software\microsoft\ril\operator names" , but for WM2003SE is completely useless.

How can i change the mobile operator names please ?

I solved the problem, the registry hack works.
