Well, there's been the PSP Slim (obviously) and the Pandora, which you may have heard about - it can unbrick / downgrade ANY PSP*!

*Terms and conditions apply. Standard line rate is 35p/$2.40 a minute. You must be over the legal age of 18 to participate. Enjoy alcohol responsibly. What I mean to say: it doesn't work for PSPs that have been bricked by a corrupt idstorage (v. rare).
