HTC is indeed preparing a pair of Android handsets with dedicated Facebook buttons, and they are pictured above and below. While no specs were available, it is clear from the images that one is a QWERTY candybar a la the Motorola Droid Pro, while the other is a more traditional touchscreen slate.

Reports first circulated by British financial publication City A.M. — which also tipped the Google Nexus S — claim that these models are running modified versions of Android, although the not-yet-announced Sense seems to be present on the slate, streaming Facebook updates directly to the clock widget. According to a BGR report, people who have focus grouped the phones say that they have minimal storage and always-on GPS radios, and that the cameras upload images directly to Facebook.

We’re expecting more details at HTC’s MWC press conference tomorrow.

Update: We hear that the one with the keyboard is the HTC Snap 2 (even though the first Snap was a Windows Mobile phone), while the full touchscreen will be known as the HTC Icon.

Update 2: The Seattle Times has the full scoop on these handsets (apparently called ChaCha and Salsa for the 2.6-inch QWERTY touchscreen and 3.4-inch full touchscreen, respectively), which interestingly, are said to run Android 2.4 (Ice Cream? Gingerbread redux?). Both phones will supposedly arrive in the second quarter.
