Leaked images of unannounced devices aren't uncommon, but they always seem to make waves in the blogosphere. But the waves are a little higher when an unannounced device is caught on camera by another secret device. Speculation suggests the handset we're seeing here is the Sony Ericsson Hallon -- a yet-to-be announced device toting Gingerbread and front-and-rear cameras.
The device responsible for capturing these images is believed to be the Sony Ericsson Anzu -- which is rumored to be the successor to the Xperia X10. Formerly referred to as the X12, the Sony Ericsson Anzu is said to have a 12-megapixel camera. However, the resolution of the images that appeared on Picasa were 8-megapixels. So either these shots weren't shot at maximum resolution, or Sony Ericsson went with a lower-spec camera. And for all we know, these images could have been captured with a completely different device altogether.
