To change the carrier logos (manually), you just need to modify the files in your carrier bundle, and then add the "@2x" suffix at the end of the file name.
For example, my carrier is Bell. I have the following files in the Bell carrier bundle:
Default_CARRIER_Bell_1only_.png (21x20px)
FSO_CARRIER_Bell_1only_.png (21x20px)
TS_CARRIER_Bell_1only_.png (23x20px)
So I replaced them with the following:
Default_CARRIER_Bell_1only_@2x.png (23x40px)
FSO_CARRIER_Bell_1only_@2x.png (23x40px)
TS_CARRIER_Bell_1only_@2x.png (23x40px)
After replacing the images, toggle your phone in Airplane mode briefly (wait till you see your carrier disappear from the preference list). When you reconnect to your carrier, the new images will be displayed (no need for a reboot or a respring; they are not cached)
