im on 4.46 on my jailbreak, i installed the PSITA package. first i go to rebug toolbox and scroll all the way to the right, and fin change active PS3ID. and select CEX if it asks you to put a flashdrive in, just click no. then you exit rebug from the exit button to the left (start screen)! now you need to open PSITA and press triangle and go to network tools --> and click restore original Console ID (EID5). once thats done you can try connect to PSN

this method works for me
