ZTE Open is the first official Firefox OS phone (hands-on)

Mozilla’s preparing to make some big announcements at Mobile World Congress, but it’s let one cat out of the bag ahead of its press conference. The ZTE Open is the first phone we’ve seen running Firefox OS other than a few developer units, and just as we figured it’s an extremely low-end device. It’s very small, and feels pretty good to hold, but we immediately noticed its washed-out screen. Details are scarce for the moment, but we’ve heard rumblings that the Open is running a Cortex A5 processor, has a 3.5-inch HVGA touchscreen display, and is reminiscent of Android phones from several years ago.
