Running Android 2.3 and available in a variety of cool colors is the Xperia Ray from Sony Ericsson, which in November went all in with Android 4.0, announcing that it would bring Ice Cream Sandwich to all of its Xperia smartphones. Just 4 x 3 inches and a third of an inch thick, the Xperia Ray is the smallest of the cool smartphones this year, yet its 854 x 480 screen is among the most pixel-packed and driven by Sony's Bravia engine and an Adreno 205 GPU. That's integrated with its 1-GHz Snapdragon SoC, running apps on 512 MB of system memory, 320 MB of internal storage and 4 GB to 8 GB of included MicroSD-based additional storage expandable to 32 GB.
Its 8.1 MP back camera with Sony’s Exmor R sensor and video light captures high-resolution photos as well as 720p video at 30 frames-per-second. Also included in the tiny package are a 1.4-MP front camera, stereo FM radio, WiFi b/g/n, A-GPS, USB hosting, DLNA playback, Bluetooth 2.1 and support for GSM/GPRA/EDGE, UMTS/HSPA networks.
