Mozilla CEO expects Firefox OS phones for US in 2014
That will come after the first wave of Firefox phones hits Europe around the Summer of this year. Firefox will obviously try to launch in places where Android and iOS haven’t yet developed a strong grip on the market, and that’s a challenging task.
Kovacs hasn’t yet announced which carriers will get the Firefox phones in the States, but judging from the fact that Sprint was one of the special guests at the event, we guess it’d be the Now Network.
