I addressed this specific question a few weeks ago, and no one else jumped on it, so here goes.
My personal take on the issue is that a person's intelligence can only be trained by USING that intelligence. IQ measures a lot of different things, mostly problem-solving, spatial/manipulation problems and whatnot, which are certain skills that come with time and experience. You can't boost your IQ just by listening to someone say that your IQ will be boosted.
HOWEVER! There have been tons of stories around the internet about isochronic tones and other similar "meditation tracks" helping people focus during their work, which will allow you to use what IQ you do have trained in a more effective way. When you are clear headed and can focus on the task at hand, you will be able to perform better, so even if you DON'T know something, you will still pick it up much more quickly than without.
But hey, I'd really love to see some convincing data using a massive test pool of people who listen to suggestions to boost IQ being effective or not. I think too many claims in the modern hypnosis community (at least this one here) go unchallenged, and so we get threads like "can hypnosis do X" all the time.
