The previous Windows Phone of HTC was announced in April 2009. The smartphone producers from Taiwan are assumable working on a clamshell named Leo, but there is more smartphone news!
The HTC Leo is probably a Windows Phone with a clamshell design. And there are not that many clamshell smartphones out there. The first clues were found in a ROM. The HTC Leo will probably have a WVGA display 16:9. And it is going to have a secondary display as well, with a QVGA resolution.
The HTC Leo is also supporting OpenGL 2.0 and has a fast Qualcomm Snapdragon processor.
We do not know much about the Click, Mega or Rome, although rumours are indicating that the Click is going to become a low-end Android phone. We will keep you updated!
