Fan Phone

It came to my attention some time ago that during season four of 24 the writers included a real cell phone number. fan quickly spotted this and the writers have recieved hundreds of calls. some fans got to talk to Calos Bernard and many more. FYI that number is 310 597 3781. i dont know if that number is currently still working. now this is something that i spotting during season 3, but does not seem to out there on the net. chase calls jack and the number 818 749 5115 appears on the screen of Jacks phone. is this a fan phone also? i cant afford to phone the U.S. to find out but if any one has further info on that do comment.
