System Update 3.01 Now Available via Network Update
Just as anticipated (well...a little earlier than anticipated) sony has released System Update 3.01 and it is now available via the Network Update feature on your PSP. As of right now this just appears to be a security patch so don't expect any new features. You can get the update network update or via the download link below. Again, don't expect to be able to run homebrew after updating.
