know more about the fsf librephone?

The answer to someone who asked about this on the FSF associate member forum was "This will be a long-term project with a slow start. Initially, it will be a technical webpage with information discovered through reverse-engineering."

I wonder if this will mean anything, or if it will just be wifi only.

If the 2nd, I don't know if it will be useful in many situations

I asked the FSF and they said I should wait some more time. Maybe to the FSF40 hackathon?

When pinephone was a thing, I am not sure but I think it was the postmarket os people who said a free software system supporting all devices on the phone except the modem appeared to be a possibility. At the time I had a conversation with an university professor working on 5g software. He said in principle making a free software modem in europe is a possibility. Because lawmakers had framed the laws governing the modem matter such that there was a degree of openness in order to inspire different phone manufactures to compete. So far I have heard of no free software modem.
