Firefox OS reference phone, the Flame, is nearly out of stock. We have begun a collection program to get back unused Flames so we can re-flash them and send them to community members but we no longer have the Flame stocks to support events with large numbers of Flames distributed.
If you need a Flame, or maybe even two, you can probably still get it from me as they are returned to me by others and get re-flashed with recent builds. But I probably cannot give you a box of a dozen or two dozen Flames for your event. I’m sorry about that, we’ve simply run out.
