It looks like HTC is about to put a new kid on the block with some serious horsepower and bandwidth capabilities. According to a tipster and Droid Sans, the company is testing a new Android device capable of DC-HSPA+ speeds (in Thailand at least), which means a theoretical possibility of 42Mbps data transfers.

The phone in the photos matches previously leaked specs of the HTC Ruby (which the rumor mill says may be called the Amaze 4G for T-Mobile), with a match on the 4.3-inch, 960 x 540 qHD display, 8-megapixel camera with dual LED flash, and a 1.5GHz dual-core CPU. The phone also has 1GB of RAM inside, as well as 16GB of storage. We're told the device is running Android 2.3 with Sense 3.5, though Sense doesn't appear to be enabled on the prototype being toyed around with in these photos. That's not totally surprising, as HTC-made, T-Mobile-branded devices only adopt some of the Sense functionality.

The device in these photos appears to be a different color variation than a previously-spied model, though the industrial design of the two units closely matches.

We're digging around for more info on this phone as we type, but until then, feast your eyes on the gallery below.
