(adsbygoogle = window.adsbygoogle || []).push({}); So I have tried going into IRISMAN and restoring my CID then setting it as the one I was just using, but it still doesn't work. Any suggestions.

First off, is the cid a psp id or a ps3 one? This might be the issue.

It is a psp

The CID is from a PSP, yes.

Okay, let's go with this hypothesis. Sony somehow patched using PSP cids on PS3, resulting in invalid cid. Y'know like how they prevented users from syncing trophies until we all moved to Habib? I have this theory, because a friend of mine has about 3 or so psp CIDs, and all of them gave him invalid error, the same as yours. When he used his only PS3 cid, it worked and let him go online.

Interesting.

It must have been today because I was online using it yesterday. Anyone else have any ideas?

Yep happened last night yesterday. But that makes all psp cids worthless now lol.

Really sucks, because I don't have any jailbreakable PS3s laying around. Oh well.

But we'll wait for others to tell their opinions, before a staff may close it. :/
