It rarely gets cold enough here in Texas to need gloves. It was 80-degrees out yesterday for instance and only a bit cooler today. I can appreciate cold weather though because we do get it on occasion and I can see where users in really cold locations would have a hard time working their iPhone with gloves on since they would have to take the gloves off each time. A new app called NoseDial has surfaced that lets you dial the iPhone without using your fingers.
The app has a large list of icons for your contacts that are sized for hitting with your nose. The contacts can be navigated by tilting the iPhone. The big question in my mind is how users will unlock their phone, I guess you will have to do that with your noise and then find the page with the app using your nose, and then hit the icon with your nose to launch NoseDial.
If your nose is running, this app will be really gross. The app will sell for 99 cents and is on the app store right now for you to download. You can determine how many contacts are on each page and the size of the icons too.
