A note to you clandestine types everywhere: If you pull an unannounced, unreleased phone out of your pocket on the subway, someone's going to take a picture of it. Such is the case with this HTC device (note the telltale serial number on the bottom), which was spied in a Taipei subway. It's clearly buttonless and appears to have a front-facing camera and shares some lines of the Thunderbolt on Verizon, but this is obviously a different device.
Will we see it in a couple week at Mobile World Congress? Only one way to find out. One more pic's after the break. [Engadget]
