It was only a couple of weeks ago that we got an early peek of T-Mobile's Xperia Z thanks to the FCC, but we've now already gotten word of another unannounced Sony handset. While the published FCC report doesn't offer much more than a label, Blog of Mobile has turned up some images of what's purported to be the Xperia UL (codenamed "Gaga"), giving us an early look at the 5-inch device clearly inspired by other members of the family design-wise. What's more, the UL is allegedly sporting Qualcomm's Snapdragon 600 chip, along with 2GB of RAM, 32GB of built-in storage, a 2,300mAh battery and waterproof / dustproof attributes (these being common Japanese standards). Word on the internet is the Xperia UL will be launching as a KDDI exclusive, though we'll have to wait for something more concrete to see if that's indeed the case. Until then, you can peruse the gallery after the break to get a slight idea of what to expect.
