The Software Development Kit (SDK) and preview installation images for Ubuntu Touch have been released. Ubuntu Touch is the umbrella name for Ubuntu for Phone and Ubuntu for Tablets. Both platforms were released this year, with the latter coming just a few days ago.

This is a developer preview release for the code-happy to mess with. But since Canonical does not have its own hardware for its platforms, developers can only install (flash) them on existing hardware. Currently, only four devices are supported – the Galaxy Nexus, Nexus 4, Nexus 7, and the Nexus 10. Flashing or installation guide for all devices available here.

Mark Shuttleworth and his crew appear to have most of the pieces to one-up industry leaders in the mobile arena, but something is missing. Without that missing piece, it’s going to be tough sledding for his company. And that missing ingredient? His own hardware – a Ubuntu phone or tablet. More on that in a future article.
