Sony Ericsson has announced an upgraded version of the popular Xperia Arc, somewhat predictably calling it the Xperia Arc S.

The new phone will feature an upgraded processor, all the way up to a 1.4GHz processor, and will reportedly have a UK release date of October.

Sony claims this will lead to a 25% increase in general speed (including camera start up and media conversion), and a 20% upgrade to page rendering speeds for the internet browser.

The slim handset, which is sadly only single core still, gets an upgrade in features, including the ability to take 2D and 3D pictures in panorama mode.

When is 3D not 3D?

It's not 'proper' 3D though, as it still takes the 2D images and then uses image processing to make them pop out of your 3D enabled TV.

The Sony Ericsson Xperia Arc S offers the same powerful features as the original Arc, incluing the Bravia and Exmor R engines for enhanced image quality and photography - with an 8.1MP plus LED flash sensor to match the original.

Featuring the latest Android 2.3.4 update to Google's mobile OS, Sony Ericsson is clearly still pushing ahead with its promise to release phones with with the latest Android update - plus Facebook inside will keep the social network-lovers among us content.

We've no word on price yet, but we can't see this one debuting above £30 per month on contract - stay tuned for our hands on Sony Ericsson Xperia Arc review.
