I always have my iPhone in my Jeans-Pocket. Today I wanted to get my iPhone out of my pocket. When my hand was in my pocket, I touched the headphone jack with my finger and lost a piece of my skin on my finger. I told this to my girlfriend and she showed me her finger. She has happened the same thing a few days ago.
The jack is so sharp-edged that it is really dangerous. Does anybody else have had the same issue?
