PS3 System Software Features
Version 4.90
As always, it's NEVER a wise idea to update PlayStation Firmware in order to make use of such things as PS3 Custom Firmware (CFW), downgrading, homebrew, Webkit exploits, etc for those in the PS3Scene.
The PS3 and PSVita forums were closed last year to new posts / replies and set to read-only for archival purposes, so only articles with no comments are periodically added in these sections now.
