Oh yes, Skype for your PSP-2000 (aka, PSP Slim & Lite) series is now a reality. At least outside of Japan. It's only available via network update at the moment and adds expanded support for PLAYSTATION Network titles. You do have your $20 PSP Headset right? Good, so what are you waiting for punk, get outta here and let us know how it goes.
