Sony has released its new PSP firmware 2.80 update today. You can download it using the Network Update feature in your PSP.
When updating, the firmware reads it contains the following features:
- 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.)
[update 1: Fixed a misspelled word and hopefully clarified the post a bit.]
