Software company Mozilla has made a reference design of it its Flame smartphone available to order online, primarily as a reference design device for the developer market, but that is available for anyone to order.
The OS was previewed earlier this year, when the firm pitched it at developers.
"This week we are announcing our new Firefox OS developer preview phones because we believe that developers will help bring the power of the web mobile," Mozilla said at the time.
Some four months later Mozilla is ready to start accepting pre-orders for a handset that has been co-developed with manufacturing company T2Mobile. Mozilla calls the Flame a "reference device".
Pre-orders are available now and cost $170, via Everbuying.com, and the site ships to the UK. The phones have front and back cameras, a 4.5in screen, a Qualcomm MSM8210 Snapdragon processor, 1.2GHZ dual-core processor, 8GB memory, SD slot, 256MB - 1GB RAM, dual SIM slots and WiFi and Bluetooth connections.
While other firms have produced a Firefox phone, this is Mozilla's first. "Until now, there has been no 'reference device' and the options for getting something through retail were limited," Mozilla said in an introductory blog post.
"The Flame is representative of the mid-tier phone hardware Mozilla and its partners are targeting over the coming year. It was designed for our developer and contributor community, so we worked with the manufacturer, T2Mobile, to keep the price as low as possible.
"We're excited that we are able to bring a high quality reference device to our developer community at an affordable price."
The phones will be updated with the latest version of Firefox, and come with configurable RAM that can be used to make it mimic the specs of other hardware. The Flame is unlocked for all networks.
Mozilla reckons that once ordered a Flame will ship in around four weeks. Shipping is free.
