Hello all i just wanted to clarify psid.PSID and IDPS are very different idps is used for anything online login games purchases etc.Psid is used for offline such as content owernship raps rifs dat as well as offline saves.These are just a few as the true uses by S@ny of psid are known by S0ny alone. Npub game ownership is also saved with the psid and related offline info.This my friends is why you only need to change your idps to get online.could S1ny use this info on ps4 for something else absolutley on ps3 however only valid idps is needed.Joonie a well know dev and a big reason we have cfw to enjoy had quoted on psx place that psid has nothing at all to do with getting online.True words from a smart man 
Hope this helps
