Android Developers always want the best for their fellow Android users. It is under this premise that XDA Developers members pabx and rogro82 ported Android 4.2, the latest Jelly Bean software update, to the HTC One X. While their latest release is only an early preview of what's to come, it is definitely an innovation that can temporarily quench your thirst for the long-awaited Android 4.2 update.
At its test phase, the Android 4.2 port has wireless, phone calls, GSM data, audio output, non-HD videos, and GPS working. Unfortunately, the camera app, watching HD videos, audio recording, Bluetooth, and other unreported bugs still need attending to. In addition, you can't check your December calendar because it's entirely missing. However, the developers are working on fixing bugs in later releases so watch out for more of their updates. Regardless, if you're an owner of a One X and you're just dying to see how Android 4.2 looks on your device, then flash away.
