Hot trend alert! In Korea they are using snack sausages as styluses for their iPhones. The sausages apparently are a good substitute for your finger in size and flexibility and are ideal for Winter since the iPhone touch screen display is not responsive to gloved hands. According to this Korean article, sales of the snack sausages are up 40% over last year thanks to this growing trend. These sausages have a HUGE advantage of your fingers: in case of emergency you can always eat your stylus.
