(adsbygoogle = window.adsbygoogle || []).push({}); Do I need 2 ps3s for cod ghost hacking? Or is it now possible to go online with a CFW? If yes are there any risks or is it better to have one PS3 with CFW and one with OFW? Someone please reply because I'm planing on buying a jailbroken PS3 on ebay.

You dont need 2 ps3s, you can go online with the CFW

What if a update comes out for PS3 4.51? Will I have to wait for a another DEX CFW to come out?

No, they would be able to spoof the newer version.
