Jolla is partnering with Sony via Sony's Open Devices Programme. The first supported Sony device is the Xperia X with others to follow.
Certainly looks to be a handset with good hardware to show off Sailfish OS (SFOS).
Sailfish by Jolla is developed from Nokia's very slick Meego OS.
Sailfish has it's own ever increasing number of native apps, but can also run Android apps from third party Android stores. Apps can also be side loaded, meaning apps not present from the the third party stores can still be installed.
SFOS for the Xperia X is expected to be available some time in the next few months. I know I'll be watching out keenly for it's release. The Jolla C (Intex AquaFish) handset doesn't do the OS justice.
