Sony Xperia SX
The Sony Xperia SX is the Xperia GX's smaller brother, but it has its own lures. It is not only an LTE-capable phone, but it is the world's lightest one, weighing in at 95 grams.
Other specs include a 1.5 GHz dual-core processor, a 3.7-inch display, an 8 MP camera and Android 4.0. And the device is set for a summer release, along with the Xperia GX.
