Activating and Deactivating Your PS3 System, What You Really NEED To Know
Posted on December 30th, 2008 by thatruth2006
Update: After another 1hr 40 min conversation with Sony and after finally getting to speak to a manager they deactivated by old system. In the end, I didn’t have the old receipt, but I had the new one so faxing them that plus my name, PSN ID, sign-in ID, name, phone number, and a service request number they gave me got it got done. I sent the fax about 11 a.m. this morning, they sent a response email saying it was done at 2pm, so quick turnaround. I get home and tried to activate my PS3 and wouldn’t you know now it works like a charm, but man this is something I will never forget.
