It's been seven long weeks since Sony last updated PSP's firmware to version 3.11. The extended lapse between then and today's firmware v3.30 could be a sign of two factors at play: 1) 3.11 actually secured the handheld (for almost 2 months), despite the firmware being quickly decrypted; and 2) compatibility issues weren't plaguing downloadable PS1 titles (because there weren't any new ones(!) -- unless you count WipEout). So what does 3.30 offer users besides the obvious security patch and extended PSN support? Not much:

• Support for thumbnail images of items has been added under [RSS Channel]
• Support for thumbnail images of videos that are stored in the "VIDEO" folder has been added
• The following sizes of MPEG-4/H.264 AVC Main Profile (AVC CABAC) video files can now be played in the "VIDEO" folder: 720X480, 352X480, and 480X272 (native resolution)
  
• [Use Wireless Hotspot] has been added as a feature under [Network Settings]

The expanded video size options are the most notable addition, but IGN reports that the feature is "very touchy" (read: it has yet to work with IGN's user-created files). But the added resolutions, particularly 720x480, could foreshadow a pending Remote Play update enabling DVD playback (via PlayStation 3). Download here.

Update: corrected Remote Play analysis. [Thanks, Zamfir]
