Right. So I was thinking of buying this:

Datel Battery Slim PSP Tool - Pandoras Battery

Mostly because I have a distinct feeling that I would break the battery before I would be doing the process correctly.

I would probably use this guide to do the whole magic memory stick and custom firmware switchover:

Easy-To-Use Pandora's Battery Guide - PSPMod.com - Sony PSP Mod & Hacks Forums

If you have a chance, let me know if that is a good one or if you know of a better guide.

So once I have the pandora's battery, I need to do the magic memory stick thing. Seems easy enough that I could do it.

Is the pandora's battery still good to use as your everyday battery even after it has been used for the mod?

Yeah, I know, lots of questions.

Thanks for the help though!
