The 4.21 is a optional update to improve system stability thats all this is update is for. IT IS OPTIONAL!!! I am sure if there was a problem with CFW users getting on PSN this would be the place to find out.
As soon as I knew of this update I tested 2 of the 3 working methods getting CFW users on PSN and this update doesn't affect CFW users. I am not saying that this is concrete proof but as of now it has no affect to CFW users.
As always if the system asks to update while on FckPSN, PSON, etc. DO NOT UPDATE!!!! Wait until there is another CFW solution is out.
what cfw you on? did try using fckpsn yet? There is a revision to PSoN you might want to try that as well only if your on kmeaw 3.55 cfw
just checked fckpsn 0.08 and as far as what I have been reading all other known methods of getting on PSN isn't working either, looks like sony did put another screwing to CFW users! All we can do now is wait and see if there is going to be another fix for PSN ACCESS. It was fun while it lasted I guess...
