I just was sitting there, looked at my ps2 controller and went 'wait a second, there has to be got to be something in common here.' and after testing different possible button combos, I got this:L+R(hold) and at the same time press X, X, B, B, X. There you go, when you continue game(btw you have to enter this code in the compstat screen, when you enter the cheat the button combo in progress will appear in the box at bottom of screen) you should get a phone call.
