Looks like we've got a new unannounced Sony handset to keep track of. A new listing over at the Bluetooth Special Interest Group's website has revealed the Sony LT30, a handset that's described as being part of Sony's "premium product line." The LT30 is said to feature "an attractive ARC design" as well as a metal rear cover. As far as actual specs go, the LT30 reportedly packs a 4.6-inch 1280x720 display, 13-megapixel rear camera with 1080p video recording, a front-facing shooter that can capture 720p video and a body that measures 9mm thick. Some user agent profiles allegedly belonging to different LT30 variants (LT30a, LT30at, LT30p) suggest that the device will also feature a Snapdragon S4 processor and Android 4.0.

So has your interest been piqued by this LT30? If so, hopefully you don't mind a little more mystery in your life, because so far there's no word on when the LT30 might launch or even what its name will be when it does. Now that the LT30 has been given the Bluetooth SIG's stamp of approval, though, it's at least another step closer to hitting shelves. Stay tuned for more details on the Sony LT30 as we get 'em.
