Re: waiting for freakin phone calls...
I know what you're going through. It's annoying when they don't call you isn't it? I also agree on the time factor. One trick you could try is save your game before you get the phone call, then when you get the phone call and it doesn't say the right Pokemon is swarming, turn off the game/turn it on, and take the phone call again over and over until you get that swarm. I heard in Platinum that you can do that around the millionaire of that Pokemansion until he said the right Pokemon is swarming.
