This is pretty neat, but I think I will stick with Firmware 1.5 that came on my PSP when I bought it the 1st day they came out. I haven't made one Firmware upgrade to mine.
Anyhow, Engadget brings word that the PSP 3.90 Firmware is out now and adds Skype...
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.
