Sony announces Xperia Go and Xperia acro S: waterproof and dual-core

If you were underwhelmed by the middling specs of Sony's past toughphones, you might want to take a look at the latest pair to join the 2012 Xperia family. First up, the Xperia go houses a 3.5-inch 480 x 320 display with a dual-core 1GHz processor, powering the (unfortunately still) Gingerbread interface. Sony has reiterated that Android 4.0 will find its way to both new devices. The Xperia go also throws in a 5-megapixel camera and the same wet finger tracking seen on the Xperia Active, which will mean the phone can be steered during underwater adventures. You be able to pick from white, black and yellow color options when the phone arrives in Q3 this year.

The Xperia acro S bumps the screen resolution up to 720p, slathered across a 4.3-inch surface, alongside a 12-megapixel camera and dedicated shutter button. It appears to be the global version of the Japan-only Xperia acro HD and arrives PlayStation-certified. Like the Xperia go, it totes IP55 and IP57 ratings for dust and water resistance, plus NFC capability of Sony's SmartTags. The Xperia acro S will land in black, white and pink color options -- but we're still waiting to hear more precise availability details. Video tours for both handsets are right after the break.

Update: We've been told that the Xperia go will launch as the Xperia advance in the US -- but dates and prices remain a mystery.
