After searching for a month, i waz able to find these cabs posted in some site.
Install the Video Telephony Cab and then install if necessary the Slide to Answer Cab.
Keep in mind that when u install the video telephony cab, your taskbar icons above get back to the default wm 6 white icons......

"I have Tried it in my HTC Touch Pro GSM and its working very good, but its kind of sluggish during start up "After Boot".
Please try the cabs with your own risk.
