The Xperia E, Sony's low-end Jelly Bean-powered smartphone which was announced back in December may have another trick up its sleeve yet. The manufacturer is offering owners of the device the chance to test out Mozilla's fledgling Firefox OS on the device via a downloadable ROM. Meant for "advanced developers," the ROM comes with a few warnings from Sony, chiefly that you should know what you're doing before you get started.
The ROM is thus far labeled "experimental," and comes with its own set of limitations: for starters, there's no radio connectivity. This means no cellular, Wi-Fi, or Bluetooth capability. Additionally, the SD card "might be unstable" and touch screen sensitivity is not fully calibrated.
