See by the time you made this thread you would have found out the answer. This question is everywhere.
Anyways it depends if you have a phat or slim 2000 then yes you can get to 4.01m33 by using a pandora battery and magic memory stick. If you have a psp3000 which is the latest one, then you can not get to m33 even with the pandora battery and magic memory stick...Yet!!!
Well that should have answered your question.
