Chinese manufacturer ZTE is one of these finger-in-every-pie OEMs, currently pledging allegiance to both Android and Windows Phone.
Now we’re hearing that it’s working alongside Mozilla with the aim of churning out a Firefox OS-based smartphone in early 2013.
Over on WSJ, ZTE spokesman David Dai Shu screams: "We are trying to increase our efforts in coming up with our own operating system, while introducing products based on Android.
"It's all part of our wider plans to create a better balance of products using various operating systems. We won't just rely on Android or Windows."
Of course, Android OEMs fear Apple’s wrath (though Samsung is bearing the brunt for now), while Microsoft demands a meaty licence fee for Windows Phone.
Back in July, Mozilla was saying there was a ton of support for Firefox OS, including Deutsche Telekom, Etisalat, Smart, Sprint, Telecom Italia, Telefonica and Teleno, and manufacturers TCL Communication Technology and – as evidenced above – ZTE.
