PSP firmware 3.60 reveals hidden USB Charge feature
Andrew Yoon over at PSP Fanboy
got his hands on the redesigned PSP and has posted a few tidbits on the site. Most notably, there is a new USB charge feature in the new upcoming firmware 3.60. Here's what Andrew had to say about the new PSP:

We got our hands on a fully functional redesigned PSP, and we
immediately grabbed pictures of the firmware that was installed on the
system. Currently unreleased, version 3.60 was installed on the system.
All of the features that are available in 3.60 will not work on the old
PSP system, and it's unclear whether or not an older PSP system will
even display the features found in this update.

UMD Cache is used to increase the load speeds of games. As revealed earlier, the cache is added RAM found in the redesigned system.

USB Charge allows players to
charge their PSP battery by connecting their systems via USB.
Previously, the system would drain power when stuck in USB mode.

Connected Display Settings contains the settings for the new video-out feature.

Within the display settings, PSP owners can change the type of TV
that's connected, and settings for screensavers. We connected a PSP to
a TV and were impressed by the results: UMD movies look fantastic, but
games will be bordered. PSP games are rendered at 480x272, progressive
scan only. Because it's output at 480x272, there will be black borders
all around the image when playing on the television.
