Operator Logos for Nokia 8260 Cell Phones?
Chetna asks: "The Nokia 8260 has proved to be quite a nifty phone...aside from the ever-persistent operator logo that sits on my screen. I can't find anywhere a way to change the operator logo for an 8260 that runs off Rogers AT+T in Canada. The only MCC/MNC I can find is for Microcell Telecom Inc, which (I think) is the operator for the other Nokia models (61xx). Is there any way to get 'ROGERS AT&T' off my screen?"
Only GSM Phones support the logo changeing. fido uses gsm, so all their nokia phones can do it, rogers uses tdma, so its phones cant. GSM requires a sim card, where user information, such as the address book and optional logos/ringtones are stored. the good news however for you rogers users, is that they are comming out with gsm service soon, so if you subscribe to it, you get to change your logos.
Nokia phones have two different alpha tags, the first is a user configurable alpha tag associated with a NAM that is displayed when the network is found on startup. This is easy to set from the system configuration screen (type *3001#12345# to enter the system configuration mode).
The second alpha tag is the designator for the network and can be changed on some, but not all phones/networks. AT&T Wireless San Francisco (my service provider, PSID 40231) configures their network such that you can't change the tag (they disable private network access as you can see from screen 2 DCCH mode in the field test display [see URL above for instructions on entering field test mode]). For providers which do allow you to change the alpha tag, here is the procedure:
Generally speaking, the Nokia 8260 (US AMPS/TDMA/PCS TDMA) is a severely crippled version of the Nokia 82xx series. It lacks both the data cable (M2Bus, the grid of pin holes found under the battery once you take off the rear cover) and infrared interfaces that many of the GSM versions include and also has a number of fun features disabled.
