FINALLY did it. This time I waited on the bridge leading to where you get the money for awhile until suddenly Packie started talking and ran out the back way. Again the enemies kept coming, but after killing two I kept inching closer to the door until I managed to get out before anymore could appear.
EDIT: I have a stupid question. Is Sleep mode on the phone supposed to be on or off to carry on with the story? I only ask because I changed it by accident earlier, and now when I set sleep mode on, it says nothing, but when I turn it off, since I assumed that's what it's supposed to be set to, a message comes up saying to disable sleep mode you need to switch it on. So I'm pretty confused.
