Firmware 3.30 now available on Network Update

What big Microsoft news? Sony sneakily snuck out a new firmware upgrade for PSP: the first in almost two months. Here's the list of the improvements for this firmware revision:

• Support for displaying thumbnails for items has been added under [RSS Channel].
• Support for PLAYSTATION Network titles has been expanded.
• The size of videos that can be played under [Video] has been increased.
• Support for displaying thumbnails for content saved in the "VIDEO" folder of a Memory Stick has been added under [Video].

Update 2: For those without wi-fi access, the update can be downloaded here. Save it on your PSP under this directory: PSP/GAME/UPDATE. IGN is reporting that the video profiles have expanded to include 720x480 (DVD), 352x480, and 480x272 (native PSP) resolutions. However, it does not appear as though they've been successful in converting video files either. Stay tuned for more updates.
