Sony took to the stage at IFA 2011 to unveil its latest handset, the Sony Ericsson Xperia arc S. It appears to be a refresh of the original that was launched earlier this year. The super-slim device just got a few bumps in features, including a 1.4GHz Qualcomm MSM8255 processor and an 8.1 megapixel camera with an Exmor R sensor that includes a “3D sweep panorama” mode, which offers the ability to take 2D (read: not stereoscopic) images and convert them into 3D. The new device will offer a similar 4.2-inch Reality Display that we’ve seen in the original Arc, and will be available in five colors globally this October.
