Engadget has a little tips on the the unknown HTC smartphone we posted yesterday. Apparently it is likely the MDA compact IV, which is made for T-Mobile. The MDA compact IV is not announced yet too, but Engadget snapped the dummy phone pictures at a event last month.

The T-Mobile MDA compact IV will be running the new Windows Mobile 6.1, it will support HSDPA connection, come with VGA display scree, integrate GPS, WiFi and built in 4GB storage space. The MDA compact IV is exclusive for T-Mobile, other countries might see it in HTC branding.

You can refer to the unknown HTC devices again from the picture below. While the first unknown HTC smartphone at the lower row is still unknown, it does have a similar hardware design as the MDA compact IV other than the extra QWERTY sliding keyboard.
