lol no it doesn't, 4.50 requires you go into PS3ita manager and restore your original cid everytime you wanna go on PSN 4.55 allows psn access nothing else required
theres 2 options 1st option to reinstall your dex cfw to 4.46 rebug dex and then spoof it with 4.60, 2nd option is to wait for ps3ita 4.60 spoof? correct me if im wrong
