The Sony Ericsson Xperia Arc S is now available on Vodafone Online, and in stores from tomorrow. The Arc S is the same form factor and design as the original Arc but with some bumped specs including a new 1.4GHz processor and a "3D sweep panorama" mode.

The greatest weakness of the original Arc we found was the battery life, which doesn’t seem to have been improved on this model. The quoted 7 hours talk time was something we never got close to, but maybe the Arc S has some improved battery saving techniques built into it.
