Sony's as-yet-unannounced PlayStation phone could be one of the worst-kept secrets in the technology industry.

Just a couple of days after images of what appears to be a PlayStation phone leaked on a Hong Kong forum, several more photos have been published on a Chinese Web site, called IT168.

The images appear to show a PlayStation phone in full working condition. According to Engadget, which first discovered the leak, the device in the images features a 4-inch touch display, 5-megapixel camera with an LED flash, a microSD slot, and a micro-USB port, among other features.

The smartphone in the images boasts slide-out PlayStation controls, including Sony's familiar D-pad and controller buttons. The smartphone and gaming device is branded with Sony Ericsson's Xperia logo.

The phone closely resembles devices featured in previous videos and images that have hit the Web.
