How do I Jailbreak my PS3? -On 3.41 -On 3.55 Note: If you are one of the few people that still has a PS3 on 3.41, I highly suggest you to update to 3.55 and do the 3.55 Jailbreak.

If I have a Jailbroken PS3, can I still go online? Yes you can. Will I get banned if I go online with my Jailbroken PS3? If you use rebug, or whatever spoofer is being used responsibly, chances are, you won't. By responsibly I mean, at the first sign of ban waves (Try to stay up to date with the PS3 modding scene), you uninstall the .pkg and wait for more news. What is a "spoofer"? It is a hombrew application that makes your PS3 look like it's running the latest firmware, so if you're on 3.55, Sony will think you're on the latest firmware. What is a custom firmware? A custom firmware is an original firmware edited by a developer/hacker not associated with Sony that let's you do things you are not able to do while running an original firmware (Eg running homebrew, linux, etc). Which do you think is the best Firmware? In my personal opinion, Kmeaw's. There's no firmware that has something that Kmeaw's doesn't, and it has almost no brick reports.

Yes there is, you will need an E3 Flasher. I am on 3.56/3.60, what can I do?! Buy an E3 Flasher! How will I know if there's a new custom firmware for my current firmware? It will be posted by a trusted member in this section. Stop searching for them in youtube, it's the same than searching "phisher sites". Can I run Backups on my PS3? Yes. A tutorial can be found here. Is my PS3 Backwards compatible? (Can play PS2 games) You can play PS2 games on some PS3's. Simple way of knowing if you can or not: 2USB Ports? No. 4 USB Ports? Yes.

How do I host a MW2 modded lobby? You can find a tutorial here. Can I host Black Ops modded lobbies? No, there was a method but it was patched.
