A version of Ubuntu for smartphones that runs on the Samsung Galaxy Nexus handset is expected to be available for download in late February, Shuttleworth told The Wall Street Journal on Tuesday.
Why that 16-month-old device and not something else was not immediately clear, although the fact that the Galaxy Nexus was distributed as one of Google's unlocked "pure Android" flagship phones may have something to do with it.
There are also plenty of Galaxy Nexus handsets out there. By comparison, its successor, the Nexus 4, has been plagued by supply problems since it launched in November.
