The cellular side can be on a separate baseband processor that talks to the outside world using good old fashioned AT commands[1] pretending to be a serial device. At that point you don't care how proprietary it is since any kernel and userspace can work with it. The current proprietary problem area is graphics (binary blobs abound) and often some other pieces (eg bluetooth, system initialization and bootloaders) OpenMoko[2] did do open phones, although IIRC there was one proprietary piece.
