After being vilified so much for contributing to dangerous roads (along with all other smartphones, of course), the iPhone will soon turn Samaritan, and maybe help to make the roads a little safer. That’s thanks to the new Breathometer, “the world’s first smartphone breathalyzer.”
The little dongle plugs into the top of your iPhone, via the headphone jack — so it’ll work with pretty much all iPhones — and measures your blood-alcohol level after you’ve breathed into it. The results get displayed on a companion app. Brilliant.
