    I am looking to upgrade my slim from 3.71 cfw to 3.90. Can you jump straight to the new update without installing 3.80. I have the file already in my psp/game so I just need to confirm this before i proceed. Also, is it worth jumping to 3.90?

    Are you talking about 3.90M33 or 3.90? Either way you don't need to go to 3.80 first...you can skip that.
