The iPhone’s touch screen works by conducting a small electronic charge through your fingertip; most gloves that are effective insulators from the cold are also pretty good at electrical isolation, so you have to take your glove off and your hand gets cold.

South Koreans have solved the cold-weather iPhone problem: Buy a particular brand of mini sausage that’s approximately the same shape and conductivity of a human finger.

Clusterflock has a concise summary of the iPhone sausage finger. The Google-translated article leaves us with this thought: “Maekseubong tagitcheung and this just fits the iPhone user base, while the poisonous celebrity, Max is on the stick.”

This evening I wondered whether the four-conductor iPhone headsets (headphone plus microphone) could be used as conventional headphones on my computer, nevermind the mic. As it turns out, they not only work on Apple’s laptops, the mic does as well, as does the play/pause clicker. Now you can use Skype without taking off your earphones. (They’re also compatible with almost all of Apple’s iPods.)

Apple’s own documentation is sparse bordering on nonexistent. Product descriptions for their iPhone headsets only mention iPods. The most Apple has written about this is on page 25 of a PDF of the MacBook Pro user’s guide: “Audio out port: Connect external speakers, headphones (including iPhone), or digital audio equipment.“

If you haven’t got a compatible laptop, you can make an adaptor that splits into Mic In and Stereo Out plugs, or buy one.
