The HTC Radiant has gone official, except it's now called the Titan II, and it does in fact come packing Mango and LTE. Around back is a 16-megapixel camera capable of capturing 720p video and a 1.3-megapixel shooter up front for video chats. We can tell that it's packing the dual-flashes from the leak but, we're not sure about not much else -- including processor, pricing or availability. So, there it is folks -- LTE on a Windows phone, and it's appears to be quite a beast of a device.
Update: Official PR has finally hit the wires and we now know it's packing a 1.5GHz Snapdragon (single-core, of course) and a 1,730mAh battery pack. The latter necessary to keep that huge 4.7-inch display and power-sucking 4G radio humming as long as possible.
