Ok, here's the deal. I just recently upgraded to the 3G. Recently, my phone has been mysteriously making calls while in my pocket. I turned the code-lock on and it is still calling people. This happened with my original iPhone as well. I called Apple and they said it could be something magnetic in my pocket. They advised me to go to the genius bar for help. Does anybody have any tips or fixes for this, or should I just go to the genius bar?
