If present in the package, the operator logo can be installed 
only on hacked phones into this folder:
c:\private\10000850 

Logo_MCC_MNC_OTA.mbm

It has to be renamed with your operator data.
I.e. Vodafone Italy has MCC=222 MNC=10 so it will be:
Logo_222_10_OTA.mbm

If present in the package, wallpapers have to be copyed into the cellphone
and then activated. See your CellPhone manual for details.
