A 4.55-inch Android phone with 720p Reality Display from Sony Ericsson has just appeared on the official Bluetooth Special Interest Group (SIG) site of certified Bluetooth devices. The LT28at is described as an Xperia "super phone" with LTE and HSPA radios in addition to TD-SCDMA support for Chinese networks. The wording of the camera specs is confusing but would seem to indicate a front-facing camera capable of 720p video (like the Galaxy Nexus) in addition to a 13-megapixel primary camera with back-illuminated sensor and LED flash. It's also equipped with dual microphones, 2.4GHz and 5GHz 802.11n Wi-Fi, and Bluetooth 2.1. Although similar, the rumored Nozomi is said to go by model LT26i and feature a smaller display and camera. The Xperia LT28at is listed with "coming later" text and North American availability which could indicate an announcement at CES in January if we're lucky.
We're already seeing photographs on image sharing sites taken with "SEMC LT28at" cameras which you can sample below.
