Hi, I recently have been readin around the internet, and found rumors that if you go in to Ganton Gym, use the Jet Pack cheat and launch yourself up above the door you will be in "hell" and from there you can make your way to Liberty City and explore much of Portland.

Has anyone done this, if so, How did you go about doing this? I have tried over and over and cant seem to figure the damn thing out.
