Well, I am considering buying a PS3 so I need some help please. 1) Can the PS3 emulate PS2? * 2) Can the PS3 emulate PSP? * 3) What's the difference between a Jailbreak and a Custom Firmware? 4) Can I play game backups from the internal memory? if not should I just get a PS3 with a smaller memory? 5) I heard there's like a Skype for the PS3 is that true? 6) Can I put regular movies or bluray ones on the internal memory and watch them? (I mean not by buying from the PS3 shop) *I can't get a definitive answer from the internet because some say yes, some say no. Thanks in advance and excuse me for any stupid questions.
