Is the iPhone the most dangerous cell phone ever?

Dr. Joseph Mercola thinks so. He's concerned about that great modern boogeyman, cell phone radiation. But lucky for you, he's got a solution he can sell you: the Blue Tube headset.

The Blue Tube headset looks to be a 2.5 mm plug hooked into a tiny speakerbox at the other end. That speaker box then emits sound up a long, hollow tube (similar to how a stethoscope works) and into an earpiece similar to those found on higher-end headphones from Shure and Etymotic.

What exactly makes an iPhone more "dangerous" than other cell phones? Well, Dr. Mercola helpfully points out that the iPhone emits radiation way more often than other cell phones, mostly because of what he calls "data waves."

Hookay. Let's be real for a second: cellular phones do emit low-level electromagnetic (EM) radiation. I used to work as a radiological health physics technician, so I know a fair bit about radiation (which is why I used to be in that field. Not anymore). Without getting too science-lecturey about it, let's just say there's two basic types of radiation:

1. The scary kind that can turn you into a sewer mutant and/or kill you. This is called ionizing radiation. It comes from nuclear weapons, nuclear reactors, nuclear waste, nuclear medicine (I'm sensing a pattern here), x-rays, and Cleveland.

2. The not-so scary kind that doesn't do much of anything to you at all. This is called non-ionizing radiation. Sources include power lines, your computer's display, cell phones, and the North Korean government's secret mind control rays.

It seems like every other week we get to hear about how the microwave radiation from cell phones is going to cook all of our brains like popcorn, and yet over decades of cell phone use by hundreds of millions of people, it hasn't happened yet. In fact, the U.S. National Cancer Institute has said, "Studies have not shown any consistent link between cellular telephone use and cancer." If anybody should know, I think it'd be those guys.

At any rate, it's kind of unnecessary to shell out close to $30 for the Blue Tube anyway, since the iPhone comes with a perfectly decent set of headphones already; and unlike the Blue Tube, they have a built-in microphone as well. If you're really as scared of iPhone-induced brain cancer as Dr. Mercola seems to think you should be, just use the free pack-in headphones instead.

Thanks to reader Chuck Cooper for sending this in!

Those unstoppable cats over at iLounge (whom I am convinced are using genetically modified oompa loompas) have gone and reviewed themselves an Apple Bluetooth Headset. For $129, you get a pretty darn sleek headset that one-ups the competition by including only a single button for control (or perhaps that's 'one-downing' the competition...), a Dual Dock for charging both the iPhone and headset and a travel charger that can handle the same job. iLounge's verdict? Well, it's a mixed bag. The headset doesn't blaze any trails in the places it matters, such as audio quality or battery life, nor is it as functional as many would expect from a typical bluetooth headset (it doesn't even have on-board volume buttons; that's controlled from the iPhone). However, the headset's performance does rank in at around average, and the included accessories are certainly a leap beyond the rest. The headset also features some unique integration with the iPhone in that charging both via the dock or cable will display the headset's battery level right alongside the iPhone's. Also, to some people's surprise, the headset (just like most bluetooth headsets) can be paired with a Mac for audio chats with the likes of iChat and Skype.

All that said, it seems like Apple's Bluetooth Headset will be a good buy for the general customer who can make use of the rich set of extras that come with it. Personally, I'm counting my pennies for one of those Jawbone headsets with the crazy noise cancellation technology. In my opinion, every bluetooth headset on the market sucks. Period. I've tested a very hefty portion of them from the bottom of the barrel to the premium $100+ models (return policies are a beautiful thing), and they're all terrible because both the caller and myself sound horrible to each other, especially when there's anything louder than a pin dropping in the background. Given Apple's tendency to try and solve some of the major problems plaguing a particular technology or industry (i.e. - Visual Voicemail), I'm surprised they didn't at least try for something like the Jawbone with the Bluetooth Headset.

But I digress - if you're on the Apple Bluetooth Headset fence, iLounge's review might be able to help you out with the decision. Check it out.
