okay, I just found out yesterday that the PS3 was finally hacked!

which is why I just made my account now, anyways I'm buying a ps3 just because of backup manager, so I can backup my ps3 games like I did for my wii games, but anyways im getting one in four days if not sooner so I have alot of questions to ask:
1: Firmwares
1.0 what firmwares can be jailbroken and run games off backup manager?
which firmware versions can run the backup managers. If I recall correctly I believe the newest firmware is 3.55 and you cant run backup manager on it but you can jailbreak it, BUT I VERY WELL MAY BE WRONG, because if you could run backup manager and load games off it on the new one that would be awesome because you might even be able to take it ONLINE
1.1 Whats my chance of getting a firmware for backup manager from buying a PS3 slim from a local store?
I assume if I went out to a local store and bought a ps3, the firmware versions would NOT be consistent. If they would be, what firmware do they
all come with and can that firmware be jailbroken and run games off of backup manager? if not, whats my chance of getting a PS3 with a firmware that can be jailbroken, and run games off the manager
1.2 what about just asking the store for a ps3 with the firmware I want?
This might be a terrible idea, but what if I just request a local store sells me a Playstation 3 that has a firmware I want

. Theres a side to me saying
"
oh they probably don't care." and another one like
"
idk... wouldn't they have to open a brand new ps3 case if I want mine new... they'd probably say no".
so idk. but I think that would be awesome if they did because then I'd have no more worries about being stuck witch a ps3 that doesn't have a backup manager!
1.3 what should I do to try to get a PS3 with the firmware I want? (one that can run games off backup loader)
If you wanted backup manager so badly you were going to buy a PS3 just because of it, like me, what would recommend I do? how would you do your best to try to get one with a firmware that can load a game off a stable backup manager.
2: Backup Manager
2.0 Which backup manager should I get?
Backup Manager Vesion 1:
Pros: blu ray support unlike version 2
cons: when you load up backup manager (either in the menu or playing a game) and you shut off you console from there, the next time you load up backup manager, all your games will be CORRUPT FILES!!! so I'd have to he install ALL my games again.
Backup Manager Version 2:
Pros: you can shut down from within backup manager or while playing a game on backup manager and your games will not be corrupted, which would happen on version 1
cons: I heard no blu ray support
?? what?? I mean... blu ray movie or like the games will still be 1080p or whatever but they wont have the blu ray technology on them?
So right now it looks like I'd choose backup manager 2. Tell me which one you recommend and why?
2.1 Downloadable content with games on Backup Manager
Can you get DLC to work with games on Backup Manager this would be nice

. If so, what are the requirements, and how could I do it.
I know thats a TON to cover, but thanks for any help.
