SCEI announced official details today concerning the integration of Skype with the slim PSP.

As part of a firmware update scheduled for late January, Skype's introduction on the handheld will come equipped with many of the features available in Skype's standard PC setup, including free Skype-to-Skype calls, SkypeOut and SkypeIn for calls to and from landlines and mobile phones, and the ability to create and maintain account information via the PSP.

As previously mentioned, this latest addition to the PSP's built-in functionality is only available on the redesigned PSP. Skype on PSP will also require a Memory Stick Duo and a compatible audio input device—the most likely candidate being the recently revealed PSP USB Microphone peripheral.
