Hot on the heals of the news that the Google Experience HTC One is official comes a Sense leak for 4.2.2. Unlike Samsung, leaked HTC ROM’s don’t come out all that often so this is actually a decent find. It also suggests that the final release is probably pretty close and could be out before the Google Experience version goes on sale.
The leak is for the U version of the device, which is GSM only (no LTE) so for most folk it will need to be ported before it will run. Work on porting the ROM is already underway so expect releases on XDA over the next few days.
