Yes, i can confirm that the front camera, capable for 3G video calls is absent. Ppl who own Diamond II or any of the HTC recent devices, like Touch Cruise 09, on the key calling pad, on the bottom right corner there is a slider where u can actually shift from classic voice to video calls. Well that also proves that Leo doesn't have this option, on the contrary, that slider is replaced between voice calls and conference calls
On top left of the device on the other hand there r two non-obvious to human's eyes, led sensors, responsible for screen's auto on-off while calling, like iPhone, in order screen buttons, not to be pushed.
