I plan on buying a PSP but I am a bit confused, are all PSPs 2004 hackable? Here is my situation, I read about ChickenHen and it seems to work on all PSP 3000s till firmware 5.03. Does that mean all 2000 versions are also hackable without pandora battery? I see they have PSP 2004(EU) for 130 euros but I wasnt sure if I should buy because I wasnt sure if it was hackable, A downgraded PSP costs 190 euros, A new PSP(with latest version costs 125 euros). If not all are hackable how do I check if it is in store? Sorry for my bad English, Thank You.
