I've a 6230 and with previuous firmware version 3.17 it was possible to see and modify operator Logo (Italian TIM branded).
I've made update the mobile to v. 4.44 and seems that there no possibilities to have operator logo.
In setting of display, as select operator logo it answer me with message "No logos in phone memory".
I've request from wap site of nokia a operator logo, it arrived and I save it, but nothing has changed.
I've also tryed with application like MobiMB 2.2 and Oxygen 2.5 but nothing seems to succed in showing the logo on the phone.
Anyone could help me?
