I'm Looking around on eBay for a PSP. I'd like to play Homebrew, ISO/CSO, etc using the memory cards. What FW version should I look for, and is there anything else I might need to know? There are some with 1.5, but read on here briefly that 3.03 works? Some people say they can flash to any FW version also. Should I just get a 1.5 and flash up to that 3.03 version? Sorry if any of this information has been posted elsewhere, if so, just point me there. Thanks.
