So I was getting off a plane yesterday and ran into an old friend. We chatted for a few minutes but we both had to go. Later in the cab, I pulled out my iPhone and his contact info was showing up in my "favorites" (note I only have 3 and it was right there at the bottom. I didn't have his contact info prior to this, didn't ask or accept it, and certainly didn't make it a favorite. . .? What setting or what do I have open that allowed this?
