I wonder what would happen if I upload a video to youtube entitled "4.21 CFW - HOW TO" that says:
"Hello. In order to install the CFW, you have to shake the PS3 as fast as you can". And the following 10 minutes is a video of me literally shaking my PS3. Then, after a camera cut, the CFW appears and I have PSN.
I bet somebody around the world would start shaking its PS3 like mad hahaha.
