I have it running with Jolla's current SailFish OS. This requires a downgrade of the Fairphone OS to v1.4.2 via fastboot (Prog is available for Linux & Windows). Then you can throw Sailfish on top, the whole thing takes <15 min. Since then Sailfish runs fully functional.
Instructions can be found here:

The only question is when ^^ it might take a while ^^ maybe Digitec will do something ^^ Hope you read it ^^
