Yes, I get that. Maybe it's time the devices (being more and more smartphones, with sufficient amount of grunt) get redesigned so that link layer encryption can change cyphers at will as well.

thats done in the baseband chip, generally a separate ARM in a sealed env that talks to the grunt processor over uarts or something similiar.
these chips generally don't have the grunt to keep multple firmwares installed.

Yeah, I get that too. Maybe it's time this gets changed so that all the processing power and flexibility available can be utilised in order to change cyphers on the fly. Ergo, my redesigned comment.
