Keep in mind if you upgrade to this, you will lose all ability to use homebrew apps and games on your PSP system (atleast for now). If you're already at 1.51 or 1.52 though, you can't use them already so feel free to upgrade.
A list of new functions for PSP system software version 2.0 is as follows:
Network
-Internet browser function (no Macromedia Flash support)
Video
-Jump function (for UMD video, UMD music)
-A-B repeat function (UMD video, UMD music, videos on Memory Stick Duo)
-4:3 screen ratio mode (for videos on Memory Stick Duo)
-Audio Options switching function (for videos on Memory Stick Duo)
-Support for MP4 (AVC) playback (for videos on Memory Stick Duo)
Audio
-Support for ATRAC3, plus sound file transfer to Memory Stick Pro Duo using Music SonicStage Version 3.2
-Support for MP4 (AAC) and WAV (Linear PCM) playback (for audio on Memory Stick Duo)
-UMD music can now be played under [Music]
Photo
-Addition of wallpaper function
-Addition of image transfer function
-Support for TIFF, GIF, PNG, and BMP file formats
Settings
-Added Korean menu option
-Added character set option
-Added "Theme Setting"
-Added "Internet Browser launch restriction" in security settings
-WPA-PSK (TKIP) security format in network settings
-Settings for Infrastructure Mode under [Network Settings] were revised to be easier to use.
-Input modes were added to the onscreen keyboard.
I hear the browser is actually really nice and that by 2.50 it will support Flash
Jap version came out not long ago at 4pm EST, so expect this one to come today around the same time.
