Is there any proof that there is not an "FM" module? I saw the verge article, and the daringfireball, but neither of those writers are technical writers. A baseband radio, on any cellular device does FM modulation for the QAM/QPSK symbol decoding at base frequencies that would handily cover the FM band. Of course this may still not be possible due to the baseband processor's capabilities, but I'd like some technical data that proves this.
