Ok guys i got great news for anyone on ps3ita 4.50 dex as far as i know the cid isn't really banned you get signed out and error code 8002a224 or access to psn by this console has been banned, however i tried again on same private cid that i thought got banned but it let me sign in. Ok so this is what you have to do
step 1. Make sure you got cfw setup v4.9.9 from ps3ita installed.
Step 2. Run program on your ps3 make sure your internet connection is disabled for extra precaution.
Step 3. Spoof to 4.70 if you haven't done so then wait for reboot.
Step 4. Download psn patch 4.66.40, run and install
step 5. On psn patch press [ ] to spoof cid and psid, then press triangle to exit and disable cfw
step. 6 psninja first 3 clear
step 7. Sign in and enjoy psn

hope this works for most of you ita users and sorry for writing in caps lol just so people can see this is important!!!
