Jolla's Sailfish OS now ported to Nexus 4
Currently, there is only one phone that’s designed to ship with the Sailfish operating system. But Sailfish is based on open source software, and has now been successfully installed on the Google Nexus 4 smartphone. A YouTube user has posted a video showing the installation and set-up process.
Installation looks fairly easy. The developer uses ROM Manager to install the OS. The actual OS is not really shown. This video is more of a how-to for the installation process. You can flash Sailfish using ClockworkMod Recovery, one of several tools that also lets you flash many phones and tablets with custom Android ROMs and other software updates. Jolla further plans on porting Sailfish to the Nexus 5 and Nexus 7 as well. Sailfish OS is a Linux-based mobile OS that has a proprietary skin on it. Jolla puts its skin on it, but the operating system is developed in cooperation with Mer and is supported by the Sailfish Alliance. Jolla's aim is primarily to get Sailfish OS running on devices targeted at developing countries, in line with Firefox OS and Ubuntu Touch OS.
