Several videos of prototypes of Sony Ericsson’s ‘PlayStation Phone’ have emerged, giving viewers an early look at Sony’s answer to the increasing popularity of gaming on the iPhone.

Leaked photos of the ‘PlayStation Phone’ were published by Engadget in October, but hands-on videos posted to YouTube this week are the best evidence for the phone’s existence so far.

The device, which is listed as the “Zeus” model number in the video, has slide-out physical controls similar to the Sony PSP Go handheld gaming device, in addition to a touchscreen, which reportedly measures 4 inches. The slide-out controls appear to have the rumored multi-touch touchpad.

The video also corroborates rumors that the smartphone runs Google’s “Gingerbread” Android 2.3. Earlier reports indicated that the phone has a 1GHz Qualcomm chip, 512MB of RAM, a 5 megapixel camera and 1GB of internal storage.

In a second video, the user selects the “PlayStation” icon to verify the smartphone’s PlayStation functionality, though the device lacks any “content items” to display.
