After releasing the kernel source for the international version of the HTC One X (quad-core) back in early May, many AT&T One X users were left scratching their heads. Well, after a few months of waiting, HTC has finally published AT&T’s HTC One X kernel source over on their developer site, HTCDev. Those that like to tinker around with their phone’s software know that this means custom ROMs are about to get a whole lot more stable now that ROM chefs can dive into the code and apply fixes. Good times. Now we’re just waiting on the USA version of the T-Mobile HTC One S and all will be right with the world.
