You're referring to the startup logo I think.
The OP is referring to the home screen where it shows the operator that is being used, or the alpha tag. This used to be modifiable on some TDMA, CDMA, and old Nokia GSM phones. Within GSM, there are two methods to display an alpha tag. One is from the SIM, where the phone will match the MCC-MNC of the tower to a list in the SIM and display the name from there, or, if there is no name on the SIM, it will display the MCC-MNC. The other is to display an alpha tag from the tower if it is broadcasting one, or again use the MCC-MNC. All manufacturers, except for Motorola, do not allow the end-user to modify this setting easily, and on Motorola, it is a software hack.
RIM actually defaults to allowing the tower alpha tag, unless it is being used in conjuction with a Cingular card.
