That is completely UNTRUE. Upcoming support for the Xperia 10 IV and V was officially announced (by Jolla CEO Sami Pienimäki himself) at the official event Jolla Love Day 2. An official roadmap was announced, with the free SFOS version for the 10 IV and V to be released within “1-2 months”, followed by commercial support available in August 2024. Pienimäki explicitly said that “IT’S AN OFFICIAL RELEASE”.
Watch this exact part of the live stream from that event and see and listen to what’s been said and shown there.
