According to the report by unwiredview, HTC is working on a new Windows Phone 8 device codenamed HTC Tiara. This upcoming device will run Windows Phone 8 GDR2, first update for WP8 OS. The device will sport 1.2GHz Dual Core processor, 4.3 inch LCD2, 8MP camera, 1GB RAM, 8GB Storage and 1800 mAh battery. I think this device will fall in between HTC 8S and HTC 8X.
