AT&T is the premier Windows Phone partner in the U.S. and in addition to the new Nokia Lumia 900 they launched the HTC Titan II. After testing out both of the devices, I have to say I like the HTC Titan II better than the Lumia 900.
Check out my ZDNet Smartphones and Cell Phone blog post for more details on the HTC Titan II.
Here you can see three generations of HTC Windows Phone devices with the HTC HD7, HTC Radar 4G, and HTC Titan II.
The back of all three shows the similar HTC design features.
The 16 megapixel camera and flash lights are up at the top of the back.
The bottom piece is removable so you can swap out the SIM card.
The right side contains the camera capture button and long volume button.
The 3.5mm headset jack and power button are on the top of the Titan II.
The microUSB port is on the lower left side.
Here you can see the slight chin at the bottom of the Titan II.
There is some curved glass at the bottom of the front.
You may be able to see the gradient gray/silver on the back in this photo.
Here is a sample photo of my backyard taken with the Titan II.
In this photo you can see a tree, grass, fence, and other different colors captured by the Titan II.
