hey i just got a 3.60fw slim. I have been searching and can't seem to find the answer to the question... I understand that i need to have pandoras battery in order to downgrade my firmware...(which is better to downgrade or put the m33 firmware?) and also if i turn my battery into PAndora's can it still be used to just power my psp afterwards and play? (i do have a 1gb mem card it came with.) thanks in advance!
