Now What?

Ok so my pandora battery arived today and came with a jig stick. I put both in my psp and now its version is 1.5 sony firmware..... What next? i want the most out of my psp and homebrew i have been looking around and see that 3.71 m33 is the highest custom firmware version. Is this the one i want? If so how to i get from 1.5 to m33?

I'd suggest first, using a regular battery and memory stick
I've never used 3.71M33-2, but I hear it has some incapabilities with some homebrew apps. But then again that was when it came out, but I use 3.52M33-4 and it's perfectly fine for my use. Has better themes too. Just go to the tutorials section, first page, there is a tutorial on how to upgrade to 3.52M33 if you want to. If you use 3.71 you will have to install the 1.50 addon too though. There should be a tutorial for that too.
