Editor's note: Once, when I was using my iPhone to send an email to a colleague, I accidentally discovered that there was an extra line at the bottom of the email - "Sent from my iPhone". Out of curiosity, I tapped it with my finger. It turned out that there was a cursor displayed, which meant it was editable. Later, I will change it to my own name, or a sentence that I think of. However, it really takes me a lot of time to delete these words every time. When I found out later that it was the signature of the email, I modified it once in a while and filled in a personalized name.
