As Sony just released firmware 3.10 for the PS3, they just announced that firmware 6.20 for the PSP is going live tomorrow, in Japan, that is. No release date has been set for the remaining regions.
This update is a bit better then the standard "improved security" changelog.
6.20 adds another column to the XMB for the comic service which was announced at the Tokyo Game Show earlier this year.
Even though the update is going online tomorrow, comics wont be in for downloading until December 10th. The price is set to 4.70$ for a whole comic book, and within a range from 0.50$ to 1.70$ for one chapter only.
Update:
The firmware is now out for download in the Japan region. Here's the full changelog.
