There have been previous rumors speculating HTC’s new follow-up to the One X, but the recent leaks announced by Stuff are the most extensive by far.
The new device, now codenamed the “Endeavor C2”, will reportedly house a 1.7 GHz quad-core processor, an improved battery, a new color (not yet determined), and a pair of UrBeats earphones. Additionally it was noted that the HTC Endeavor C2 will be compatible with all of the One X’s accessories, most likely suggesting that the design blueprint will be essentially identical to the original One X.
It was mentioned last month that T-Mobile would be getting an upgraded version of the One X. As details continue to develop, it looks more likely that T-Mobile distributors will in fact be carrying the Endeavor C2, AKA the One X+.
A few vague international price and release details where mentioned as well, with UK network deals offering the phone for just a bit more a month than the One X. The HTC Endeavor C2 is expected to hit shelves on or before October 1.
