Pandoras battery noob help???

Hi guys. Bricked my 1.5 PSP while ago and gona give this pandoras battery a go. Few questions that I havnt been able to find an answer for though.
Firstly is there any way you can use the converted pandora battery as a normal one again?
And What sizes of memory card can you use? Ive seen some places saying only a 32 mb pro duo, and others saying any upto a 2gb???
Any help would be great here guys, Cheers Sinnie.

Im pretty sure the answer to both of these questions are in the release text for the pandora's battery by fanjita.

Yes, you can restore the battery to normal operation, using a spare 'just in case' would be a good idea.

You need a 256MB or larger memory stick pro duo.
