The Xperia Go features a 3.5in display, 1GHz dual-core processor and a 5Mp rear facing camera. Sony said it has the highest level of dust and water resistance in a smartphone with its IP67 rating. It will launch in black, white or yellow with Android 2.3 Gingerbread but will be upgradeable to 4.0 Ice Cream Sandwich.

The Xperia acro S has a similar specification to the Xperia S with a 4.3in 720p display, 1.5GHz dual-core processor and a 12Mp rear facing camera. It will come pre-loaded with Android 4.0 Ice Cream Sandwich in a choice of black, white or pink colours.

Before you get too excited, the firm has said the Xperia Go is the only one launching in the UK at the moment – much to our disappointment.
