HTC released a new version of its HTC Touch Diamond in Taiwan dubbed HTC Touch Diamond P3702.

The HTC Touch Diamond P3702 features as far as I can see the same specifications as the Touch Diamond available in several markets today.
The P3702 has a more round case design. Supposedly the Taiwanese consumer is not into diamond edges. The images published on the Taiwanese carrier site are not clearly showing the backside of the phone, so it is hard to tell how the Touch Diamond looks without diamonds. The HTC Touch Diamond P3702 is offered by Taiwan mobile.
