A late night update of the PlayStation.blog reveals that a new firmware update will hit PSP today. 3.93 will, as usual, expand support for PSN titles. However, it will also revamp the oft-forgotten internet radio feature of the handheld. According to the post, there are "20 new internet radio players to enjoy." Not only that, "the new players are organized into more specific styles of music so that PSP users can easily find what they are looking for and listen to their favorite genres." The current rendition of the radio is a bit disorganized -- anything will be undoubtedly be a step up.

Certificate Utility removed in firmware 3.40
The Korean PlayStation website has announced the arrival of yet another update to PSP's official firmware. However, unlike previous updates, this revision will actually remove some functionality from the system. We've translated the text--it appears "Certificate Utility" will no longer appear on the XMB. Rather, the information used to be available in this section will be embedded directly into the games downloaded from the PLAYSTATION Store. This is a rather minor, but puzzling change.
According to the Korean website, the firmware will be released tomorrow, 4/19.

Use Network Update to upgrade your homebrew

This is quite a novel idea. Dark_Alex has been following Sony every step of the way, releasing a new version of his Open Edition firmware almost immediately after Sony releases their official update. Now, homebrew users have a pretty ingenious way of finding out if there's a new version of Dark_Alex's homebrew-enabled firmware: use Network Update! Long considered vile by homebrew users, Xandu and Team 280 have created a plugin that allows you to use PSP's firmware checker to download Dark_Alex's latest. Ironic, no?
Check out installation details at DCEmu. Of course, be warned: tampering with the BIOS of your system can lead to a brick. Also, the general success rate of this app hasn't been too high: only about 2/3 of users seem to be able to successfully connect to the Updater.
Firmware 3.11 now available on Network Update

Yay? Download it via Network Update.
[Thanks, Rueben!]
Firmware 3.10 now available on Network Update [Update 1]

- Support for PLAYSTATION Network titles has been expanded.
- Support for the MPEG-4 AVC format has been added under [Location Free Player]
- [Dynamic Normalizer] has been added as a feature under [Sound Settings] in [Settings].
It should be noted that this upgrade will render homebrew useless on your system, and may prevent you from downgrading indefinitely. While we fully support Sony's endeavors on the system, we want you to make an educated choice before deciding to upgrade or not. Of course, this upgrade is but a taste of things to come: Sony will most likely include an even more robust feature set in the next major upgrade.
For those of you unable to access Network Update, feel free to download the upgrade from us. Connect your PSP via USB and save in PSP/GAME/UPDATE.
[Update 1: News from QJ suggests that people with custom firmware should not upgrade, as your systems may become bricked.]
