I'd suggest that you go back and understand what Linux is. It's not an operating system, it's a kernel. It's open source.

Harmattan is an UI on top of that open source kernel. Parts of Harmattan are open source, sourced from parties outside of Nokia. But the browser, the Swipe UI and a few other parts - telephony stack, drivers and other parts - are definitely not open source. There are no downloads for that stuff.

If that's the case, link us to that please.
