Hey guys.
Its been a fair while since i messed around with a psp.

Got hold of an old mates psp recently that i hacked years ago.
I was just wanting to ask if its cool to jump from 3.52 to the most recent firmware for my first gen psp.

I had a quick flick through the nub thread but couldn't get a firm answer.

Any help would be appreciated.

Cheers.
