The Xperia Go (pictured on the right above) is the more basic of the two, as it comes with Google Android 2.3 Gingerbread installed, but is listed as being a candidate for an Ice Cream Sandwich upgrade. However, this being Sony Mobile, when such an update will arrive is anyone’s guess.
The scratch-resistant 3.5-inch Reality Display screen uses the same wet-finger tracking system as the Xperia Active, and the whole device has an IP67 rating for water and dust resistance.
Inside is a 1Ghz dual-core processor, which although isn’t stated, we’d expect to be the ST-Ericsson NovaThor U8500, and on the rear is a 5-megapixel camera. The chassis is 9.8mm thick, and it’ll be available in black, white or yellow.
The Acro S is a very high-spec phone for one with water and dust resistance, in this case an improved IP55 and IP57 rating, as it has a 1.5Ghz dual-core processor (possibly a Snapdragon S4 like its close cousin, the Japan-only Xperia Acro HD) and a 4.3-inch, 720p Reality Display screen. The 12-megapixel camera will also shoot 1080p video, while the forward-facing video-call lens shoots in 720p.
Unlike the Xperia Go, the Acro S will have Android 4.0 Ice Cream Sandwich installed at the start, and instead of a yellow color scheme, it’ll add pink to the standard black or white models.
In case you’re not familiar with the intricacies of the IP rating system, the Xperia Go’s IP67 rating will see it survive a dunking for up to 30 minutes, provided the depth is no more than 1 meter, while IP55 and IP57 adds protection against streams of water and resistance to dust particles too.
Both phones are set to be released between July and September, with the Xperia Go being renamed the Xperia Advance for the US market.
