I was browsing the web when i stumble upon this site:
http://www.adventuremaker.com/
I am sure someone has posted about it before, But if you dont know what it is, it is basically a site with software and flash games developed for your 2.7+ psp. it even offers a free download for a program allowing you to make your own flash games. Again, I am sure this is old news, but it is good news none the less, especially for you 2.7+ portal devs out there.:)
