I dont know how many of you people out there are having problems using your iPhone in freezing cold conditions. I dont know whether you people know about this or not, fruit skins work as good as your finger for using the iPhone's touch screen.
I kind of discovered this during breakfast when I accidentally dropped an orange on my iPhone. I saw that the touch screen responded when the orange fell on it.
So, any one out there who feels it inconvenient to take off your gloves each time you need to operate the phone, take your glove, take a tiny bit of any fruit skin( cabbage leaf also works great). Stick whatever you have chosen on the finger tip of the glove,... and Voila! You have an iPhone compatible glove!!
Hope this trick proves to be useful.
