Sony Ericsson Xperia Arc leaked, is what we knew as Anzu
What we didn't knew is that Sony Ericsson has opted for a bizzare-looking handset with a curved form (hence the Arc name) and dimensions of 4.92 x 2.48 x 0.34 (125 x 63 x 8.7 mm). SLIM! It sports a 4.2-inch screen with a resolution of 480x854 and an 8-megapixel camera. Under the hood, the phone has a 1GHz Qualcomm processor, while Gingerbread is running the Arc show.
