The Xperia go, which features a 3.5-inch display and will be known as the Xperia advance in the United States, is powered by the Android 2.3 Gingerbread operating system (with an Ice Cream Sandwich update coming later) and has earned the IP67 certification for its protection from dust and water.

It packs a 1GHz dual-core processor, a scratch-resistant mineral glass display, and a 5-megapixel rear-facing camera. It also boasts a nifty "wet finger tracking" feature that makes capacitive touch input accurate even when the display is wet.

The Xperia acro S is the better of the two devices in terms of specifications, but it's not quite as protective as the Xperia go, achieving the lower standard IP55 and IP57 certificates instead. It features a 4.3-inch 1280 x 720 display, a 1.5GHz dual-core processor, and a 12-megapixel rear-facing camera. It will be powered by the Android 4.0 Ice Cream Sandwich operating system from day one, so you won't need to wait for the update.

Both the Xperia go and the Xperia acro S are scheduled to make their debut in Europe during the third quarter of 2012, though Sony is yet to confirm pricing.
