Hypothetically, even if the phone was still showing "Telus" in the network banner/notification area, this doesn't have anything to do wtih the Public Mobiile service. \
The identification/network name shown there is based on what is programmed in the software of the phone. While it is true that the sim card does have a pre-programmed name that overrides the names of the networks names that are in the device's software, it is still up to the device manufactuer's software to set itself to use that information from the sim.
As such, this isn't something that moderators would be able to do anything about. Personally, I prefer the real network names such as Bell, Rogers, Telus inteaad of stuff like Public Mobile, Away, or EXT. This preference is also likely why many custom ROMs will show "Telus" instead of Public Mobile even with a Public sim card insterted in the phone.
