Can I preload GTA V on PS3?

Hey guys, I recently acquired an original it for $50 that was getting the YLOD and was able to fix it! I'm a long-time GTA fan, I preordered GTA. My question is: how the hell do I preload it if possible? I assume it's going to take all day with the server load, even if use a cable? Googling my question just returns GTA V leaks due to preloading, doesn't actually tell me how to preload it.
