What's that? An HTC PI86100 Windows Phone with AT&T-specific LTE (bands 4 and 17) showing up in the hallowed halls of the FCC? Why, this must be the Titan II, announced a tad over a fortnight ago. Docs show that a production unit of the device, sporting the aforementioned LTE bands as well as 850 / 1900 3G (also AT&T compatible), is ready to take on its new Windows Phone competition sometime soon. Is it a guarantee that the phone is nigh at hand? Not quite, but at least it signifies that the 16 megapixel beast is one step closer to showing up in our hands.
