OK, what you need to do is this:

Find theacoffire's guide, use the search keywords 'pimp psp 2.71'. The thread title is something like 'Pimp my PSP! 2.71 and 1.50 firmware on same PSP', as it was made when 2.71 SE-A was released, but has been updated for up to 3.02 OE-B. However, once you're on 1.50, just follow the instructions in this thread.

And Fanjita is very much alive, and still developing for PSP, but I don't know what he's doing at the moment. His latest major release was eLoader 0.995 in November, and he released a few smaller projects later (like a decrypter for 3.00 and 3.01, and NetConfigBackup back in December).
