Here's a Friday mystery for all the sleuths out there to pore over: the Bluetooth SIG recently revealed a brand new Sony smartphone that's currently dubbed the LT30, but we're not quite sure what phone it is. The device reportedly packs a 4.6-inch display with a 720p HD resolution, a Qualcomm Snapdragon S4 processor and Android 4.0 Ice Cream Sandwich, although its actual launch name is currently unknown. According to Engadget, Sony is including the phone in its "premium product line." It reportedly measures just 9mm thick and sports a metal back cover. The mystery device sounds pretty much exactly like an Android 4.0 version of AT&T's Xperia ion, which offers the same specs but is slightly fatter than the LT30. Maybe it's a similar phone set to launch on Sprint, T-Mobile or Verizon Wireless.
