Since late March Sailfish OS has been available for Google's Nexus 4 with the Finnish company bringing Sailfish OS to Nexus devices while their flagship smart-phone remains with limited availability throughout Europe and the rest of the world.
The second update to Sailfish for the Nexus 4 was released in mid-April at version 22.214.171.124. This newest update fixes phone calls so audio now actually work, timers and alarms now work, HTMI5 video and audio work within the browser, and the update is based upon the latest Sailfish code. There is though still some known issues with securely powering off the device, phone call audio volume not changing with the volume buttons, and other bugs.
Jolla is soon expected to publish a Sailfish OS image for the Samsung Galaxy S III LTE.
More details on the latest Sailfish OS Android update can be found via this XDA developer forum thread and the Mer Project Wiki. Thanks to Roberto Colistete Jr for pointing out this latest Sailfish OS update.
