This homebrew app lets you use different 6.20 Permanent HENs in a single PSP. It works on all PSP models (1000, 2000, 3000, N1000). While the dev notes that beta testers have yet to encounter any bricks, be sure to be prepared for one in case it happens while you're using this app.
Don't forget to check the readme included in the download for additional details.
