Yep, I found a solution on how to force them to let us play homebrew on our precious PSPs. Click here and enter in a fake name (e.g. Homebrew Wanter) and your spam e-mail (an e-mail that only has spam, so when you sign up for 'free' stuff, you can use this e-mail) or your regular e-mail and enter in this message:
"PLEASE READ THIS.
Please let us play homebrew on our PSPs. We homebrew lovers mostly hate piracy. These homebrew games sometimes help the PSP (like the Dead Pixel Fixer, which fixes the dead pixels on PSP screens) and sometimes is made to let PSP owners have fun (like Beats of Rage). Plus, homebrew almost makes to PSP more popular (there was a worldwide poll of why we like our PSPs, and the most selected one was 'Because of homebrew'). Plus, homebrew isn't illegal. It's only illegal in Sony's mind. There have been breakthroughs in the homebrew world, like the eLoader (EBOOT loader, made by Fanjita) and Lua Player, and PSPKick (where you can make your own music). If you still don't want to, at least try to play one homebrew game/application. Go to PSPUpdates.com to download any one you like. PLEASE LET US HOMEBREW LOVERS PLAY HOMEBREW. We have the right and freedom to play homebrew, and we demand you let us play homebrew on out PSPs!"
If all of us send this message, Sony would eventually give up and let us. At least TRY it. We'll do it together! YEAH! HOMEBREW, HOMEBREW!
