What is there for Firmware 3.02?

I committed a regretful mistake of upgrade to version 3.02. Now I have lost all my goodies including homebrew etc etc. Please let me know what is now there to do with this version. I have played some flash games on the psp but that's about it. Can I run lua?? What other things are there to do? and are there any plans on making a downgrader for this version in the future? Thanks to everyone.

Well that was a silly move anyway if you have a ps3 you can download ps1 games and thats about it tough luck you should never upgrade.

Dont update in the future

try this jump on your psp and say without homebrew your crap then sell it and buy a different one and hope its 2.80
