I run it on v1 Patrick, I've tried it several times, some of the times it didn't work and I think this might have been due to answering the call at the wrong time? Also If you have the phone in your hand in the end cutscene it won't work. Re moving around freely during the mission I have a video on my channel demonstrating this, it's a lot of fun, It might save time, it might not. You do have to wait a bit before skipping the opening cut scene for the call to come in and you can't move too far away from the RC shop because of having the shoot the planes but doing snapshots is a possibility. Also if you have dated Katie already you'll spawn back at her house when you die and there's no traffic on the roads :P
Yeah darkgeorge12 that dude had some great times, i remember he had bmx challenge 28s and the best i could get was 34s lol
Relinking all the youtube videos would take a long time, not to mention most won't have been remembered
