HTC with a 3.7-inch SLCD and 1GHz Snapdragon processor -- sounds about right for the Desire, but this little puppy is actually running Windows Phone 7 (presumably a developer build, given the apps catalog). According to our tipster, the three buttons under the screen are touch-sensitive à la Nexus One, the camera boasts 8 megapixels of memory retention, and the "hardware is ready." What you're not seeing, however, is any sign of skinning -- no Sense on this one, we're afraid. The company is apparently in talks with two US carriers, including Verizon (we'd presume Sprint given the CDMA connection, but we've no insight here). Are we looking at the rumored VZW-bound HTC Spark from June? Unfortunately we can't confirm anything at this point, so for now, just enjoy the tantalizing snapshots.
