Unlock Exclusive Content DLC

There is a way to unlock exclusive content DLC.
It´s pretty easy & safe. Follow this steps, and yes, you will need a friend with a PS3/GTAV:

1. Create a PSN account for you, go to SONY PSN site to do it;
2. Ask your friend to logon to the PSN account you´ve created on his PS3;
3. Ask him to Play the prologe until "Franklin and Lamar" mission is complete;
4. Save the game;
5. Log in to your Rockstar Social Club via browser and link it with the PSN account you created;
6. Enjoy the DLC on PC.


If anyone of you guys have PS3/GTAV and want to help get other people exclusive content please say here. Maybe we can do 1 unlock per day. It takes around 15min i guess.

Does that also work with a rental version? Or does a single copy only provide the DLCs once?
I'd maybe try it with a version I can rent in a video store - but I won't spend money for a full version just for some items.
