dude, you cant do anything. seeing how noone has hacked the 1.51 and up. So for now, you can't do no homebrews or emulators or anything involving the packgen. Sorry man, wish you had the 1.50
There is a nice option for those of you with 2.0 firmware. Its like winpsportal. It has some nice games and links to good places for a psp web browser. There are also some online games budding up that work on the psp!
Otherwise, Sony should have officially released it by now, go to www.sony.com and you should be set. Hey man, don't feel bad about upgrading either. I was close to doing that. Was listening to a podcast and they mentioned new firmware. So I was about to download it until I googled the firmware. Good thing too, since that told me how the only thing it did was nerf homebrew ! Thank God for Google.
