Earlier this year, it was announced that Jolla and Sony are entering into a partnership to bring Sailfish OS to Xperia devices (starting with the Xperia X single SIM version). In August, Jolla revealed that Sailfish X - Sailfish OS for the Xperia X - will be paid, and available around the end of September.
Although a bit late, the new OS is now available to purchase and download. As of today, you will be able to purchase Sailfish X, and install it on your Sony Xperia X.
Installation instructions are currently only available for Windows users, with the company saying that instructions for Linux and macOS users will be made available later.
Keep in mind that the current OS release doesn't offer support for features like Bluetooth, new sensors (e.g. barometer, step counter), fingerprint, and FM-radio.
Carrying a price tag of €49.90, Sailfish X is currently only available for Xperia X users in EU, Norway, and Switzerland. To purchase the new OS, head to the Source links below.
I wish the Xperia X (F5122) was supported (Dual Sim). So close to having this yet so far. EUR49 is another bummer.
No, thx. My Xperia X works fine on latest official nougat firmware and i will wait for Oreo from Sony. This offer hardly makes sense for avg joe like me.
Bluetooth working out of the Box. SailfishOS runs great, Android Support is also working (Android 4.4.4 Alien Dalvik). Not working atm: Fingerprint scanner, Barometer, Step-Counter
