HTC Titan II
The HTC Titan II, (stylized and marketed as uppercase HTC TITAN II; previously codenamed HTC Radiant) is a smartphone designed and manufactured by HTC Corporation running the Windows Phone OS 7.5. It is the successor to the HTC Titan.
The HTC Titan II was the first Windows Phone device with support for LTE connectivity, it is sold exclusively by AT&T carrier in the United States.

Description
It was announced during the International CES 2012, and released in the United States April 8, 2012, for US$199,99 on contract.

The HTC Titan II shares much resemblance with its predecessor, the HTC Titan, though it has a 16-megapixel (compared to 8) rear camera and supports LTE.

Reception
David Pierce of The Verge in his review wrote: "There are things to like about the Titan II, but it has two fatal flaws: an operating system that’s still a cycle behind... and the competition. If you're in the market for a smartphone, be sure Windows Phone is the OS you need. At the moment it’s still in its infancy, and well behind iOS and Android in some key areas."

Brad Molen of Engadget in his review wrote: "Overall, we have very few qualms with the HTC Titan II. Despite its clumsier design, it certainly has more to offer than its predecessor, which was already considered a great phone when it was released on AT&T a scant five months ago (six months if you count the European launch). But is there any reason to fork out $200 for a Windows Phone that has roughly the same feature set as the less expensive Nokia Lumia 900, which is getting subsidized beyond our wildest dreams? Unless you're a camera enthusiast, we think your money could be put to better use elsewhere."
