I heard about the wrapped sausages and found out something which I don’t know if everyone knows … you can use American string cheese on your iPhone/iPod! I saw that the Korean ‘sausages’ were really just cheese so I tried out the American string cheese I brought with me to Korea. I may be wrong, but I ‘think’ I’m the first to confirm you can just use string cheese (instead of the Korean variety) on your iPhone instead of your fingers. Enjoy!
