now lets get an open source baseband

  Osmocom is a thing, but no idea how good it is. I've seen articles about people running cellular networks with it.

    The real issue is certification and so on. The people running small cellular networks tend to have necessary permissions or operate within certain limits. For public, general usage baseband, it will need to be at least tamper evident and you won't be able to just run your own. I'd personally be fine with auditable baseband (i.e. you can always verify what code it runs, then let's say compare to public code tree and build hashes), with possibly a signature scheme that would link builder and certifications. Then if you went to the trouble of proving you have the necessary qualifications and won't break shit, you could sign with your own certificate and take responsibility.

    Also, Qectel modems run Linux on one of the chips on the modem: https://projects.osmocom.org/projects/quectel-modems/ https://projects.osmocom.org/projects/quectel-modems/ I can't find the post right now, but there are folks reverse engineering the proprietary binaries running under Linux on the PinePhone modem (which is Qectel) and replacing them with open source versions. The Hexagon DSP is out of reach for that work though.
