How very smart of you.
Yep.
Nope. Not unless you wanna have some more issues with your PS3 (more specifically, PSN ban) and buy yet another one.
I had to buy a new PS3 because multiple things broke. BlueRay drive and such failed, as well as a myriad of other things. But anyway. I asked because Ive seen guys talk about modding the PARAM data. The PARAM data saves the users ID number and SYSTEM ID. I wanted to know if this were in fact true can you use a program to go in and change the user ID to your own as well as swap the system ID.
