Question about 4.21/4.30....
 

So besides PSN working now, All current games working without a 3.55 fix. And all previous fix PSN games no longer working without needing to be resigned. Also I seen some CFW issues,So is there a current point to upgrade? or are we better off on 3.55 til a better solution comes along?

not sure what you are referring to as a better solution. psn works, updates work, and games work, at least some of them until we can patch or fix for the new firmware. same thing like 3.55. if you really don't see any benefits then I would stay on 3.55 if I was you. some people like the fact that they can sync their account with all their trophies, so that's an advantage, also PS Vita is compatible with this firmware, if you like to remote play.

have you tested any games?

Yes I have, My biggest issue is my PSN games. Which I have resigned but they go back to demo mode.

Try looking at your buy list.
The games that you have buy still there, you just need to download again.
It happen with me when changed from kmeaw to rebug...
I don't know if you will have to recreate your current user (loosing all save games), I had to... :(

Can't speak for others but nothing can be downloaded from the store for me, even previous downloads give an error, I was hoping I could get my motorstorm RC running on cross play but the ps3 version won't verify, in all honesty I'm not bothered but would be nice to get a fix down the line.
