Sony has released firmware edition 2.80 for the PlayStation Portable. You can download it via the network feature on your PSP. The new firmware contains following features/updates:

• You can now download video and image content under [RSS Channel];
• You can now register devices via a wireless LAN access point under [LocationFree Player];
• You can now play AAC files with file extension .3gp under [Music]; and
• You can now play content saved in “Music,” “Picture” and “Video” folders on a Memory Stick. (Apparently, this means you don’t have to rename video files, and you can play them without using special folders.)
