Well for myself I would also really like to have an official Port of SFOS for the Xperia IV. Anyway, why do we always need to make a long discussion with the same arguments about that topic in other threads? @martinbook85 asked the question to @Jolla for getting an update about this topic. I think if you have concerns or whatever this can be discussed in the thread Xperia 1 IV, 5 IV and 10 IV support This would be more efficient if all related discussions and informations are located in one topic. Last but not least, the Xperia 10 V is also not in the Open Device Program.
