(adsbygoogle = window.adsbygoogle || []).push({}); I do not need to know how to do it but I want to know the reason to have a CFW PS3.

Will I be able to play online?

Will I be able to get trophies?

Will I be able to use mods? (I know I will be able to but will I earn trophies?)

Chances I will get banned?

Will I be able to copy copy-protected saves onto a USB?

Can I have a PS3 with CFW with an account to get trophies and have another PS3 with OFW with same account to play online?

If I switch to CFW, will everything be erased from my Hard drive?

And if I switch back to OFW, will my hard drive be erased?
