Yesterday a friend called and told me that she got a missed call from me yet I never called her. Then again today, another person called and said that his phone rang and he could hear background noises and it came from my number. I had not called him. Both times, my phone was holsetered and keyboard was locked. Neither of these people are in my speed dial. Neither call shows up in my phone log (when you press the green phone button to show recent calls) but they do show up when you go in "Saved Messages>ViewFolder>Phone Call Logs".
