(adsbygoogle = window.adsbygoogle || []).push({}); Ok, I'm pretty much new on the whole jailbreak subject. I've been reading all day and this is what I've come to (correct me if I'm wrong).

Jailbreaking the PS3 allows you to backup games and play them on your HDD, edit system files and other things like homebrew applications.

You need a USB Chip like PSJailbreak.
And FW V3.41


So my questions are:

1. Do I need to Jailbreak to make a CL in MW2?

2. I have FW 3.50, if I backup my PS3 and then format, will I be downgraded?

3. A friend of mine has a CL in MW2 by loading a backup from another guy, How does that work?

4. There are lots of different Chips from what I've seen, PS3Key, PSJailbreak, PS3-Break and PS3break. Whats the original and/or best?

5. What's this I hear about not being able to go online?

6. And Finally, What is PSGroove?

Any help on any question is appreciated!

u cant go online with the 3.41 firmware ps3 only the 3.50 can go online
