(adsbygoogle = window.adsbygoogle || []).push({}); I have a banned CID, because I bought the PS3 banned for $40.
I was wondering do I need a PSID AND IDPS, or just IDPS for my PS3?

You need a Console ID in order to get online. So yes, IDPS and PSID are needed.

I've been told by a few people that I don't really need a PSID, is this true though?

You just need a idps..
