Operator logos are displayed when you are logged onto the network (most of the time). Currently Nokia phones can only store a single logo, so if a logo is sent, it will simply replace the existing one. Note that you must ensure that LogoManager knows which operator you want to assign the logo to - normally this is automatically set to your home operator. If you are roaming on another network, the logo will not be displayed. If you want to send a logo to a friend on another network, please ensure that that person's operator is selected correctly in the send dialog.
