PSP 3.90 firmware update with Skype available

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.

Is the Skype capability only available on the new PSPs? I have the old PSP and downloaded an upgrade also. But I don't see any new applications.
Im looking to buy a PSP Slim, i had a fatty one couple years ago but at that moment i thought it was worthless just for the games and music (i would never buy a UMD Movie instead of a DVD) and i got rid of it. Now with all the advance homebrew stuff im thinking to give it a try.... but im looking for some info and opinion of the experts. (I own a Treo 700p also with a lot of apps in it like Internet Radio, DiVX, Messenger and SlingTV).
I want to know which of this features works with the 3.90 firmware and it's been tested by any of you:
- Skype (with Skype In)
- Youtube (compared to the Ipod and Itouch)
- MSN Messenger
- Internet Radio
- AVI DiVX Files
- any problem playing any original games after the upgrade?
I also updated to 3.90 but I don't see Skype like some people, how did it happen? (My PSP is series 2000)
