Motorola XT810 like its little sister XT806 is also meant for the Chinese market, however, XT810 is more optimized for this purpose. Regarding specs and design, they are very resembling, but XT810 is using the Android-based OPhone OS v2.0 which is proprietary to China Mobile operator. There should be integrated very much the operator's services, so the local users may be very happy with that.
