The LT28a -- not to be confused with the LT26i (Nozomi), a rumored handset with a 4.3-inch HD screen and 12MP camera -- claims to offer LTE, a 720p HD Reality display, 13MP rear camera with an LED flash and a front-facing cam capable of taking 720p HD video, and is said to take the Xperia lineup into "superphone territory."
