SmartAboutThings writes "We’ve been hearing quite a lot lately about the Firefox OS, but there are actually only a few Firefox OS phones launched on the market. ZTE Open is one of them and is actually the first Firefox OS phone for consumers. Even if Firefox OS has support from carriers all over the world, it’s pretty hard to sell devices in more locations across the world. To remedy that, ZTE is going to sell the Firefox OS Open phone on eBay for eighty dollars, which is actually ten dollars less than the launch price. A real great thing is that the handset will be off-contract and unlocked which means you will be able to use it on all mobile networks. ZTE didn’t mention when exactly the device will go on sale on eBay, the company just mentioning “soon”."
