Much like how three (or four) of the major US carriers will be getting the HTC One, China's three carriers will also be receiving the same treatment, according to the country's official device approval database. The three flavors are known as 802w, 802t and 802d, each heading to China Unicom (WCDMA), China Mobile (TD-SCDMA) and China Telecom (CDMA), respectively. For the record, the European version we have is 801n, so perhaps the third digit represents the number of SIM slots featured on the device.
This is certainly the case for the 802w. Earlier today, a Sina Weibo user posted the above photo of said phone with its back cover -- between the two plastic lines -- removed, thus exposing not only its two SIM card slots but also a microSD slot just below the camera. It's worth noting that the European version of the One doesn't come with a removable back cover, let alone a secondary SIM slot or a microSD slot; but at least it has LTE, right? Since Sina Weibo requires you to login before letting you see the post, we've got the full picture for you after the break.
