Sony Releases PSP Firmware 3.90 - SKYPE Support is Here!
Note that if you have a homebrew capable PSP, this official upgrade will (for the time being) eliminate your ability to run homebrew, so beware!
And as they promised at CES... the Skype client is included in this release. I haven't seen the microphone accessory in stores around me yet, but I'm sure it's coming... Some readers have asked me if the update only applies to the Slim - that does not appear to be the case.
Here's the official info from Sony's site:
The PSP® (PlayStation®Portable) system software update may include
security patches, new or revised settings and features and other items,
