I am a new user and this could have been some bizzare newb thing I have to look out for, but this was odd. I was talking to a friend (friend #1) for a while (no headsets or anything, just holding against the ear). Near the end of our 30 min talk, I hear another voice. Thought it was just some racket in the background, hung up on friend #1, and on the line was friend #2. Friend #2 says 'who was that you were talking to, I heard the whole conversation.' That freaked me out. Anyone accidentally do this? I doesn't seem that all the buttons you'd need to do a 3-way call would have actually be done in sequence with me not knowing and talking on the phone. What if this happened during a business call or something... I felt like I was in that Seinfeld episode where Jerry and George are on the phone and the girl on the other end of the phone heard the whole conversation.
