I have a contact in my iPhone called "Robert Aitken" who I rarely, if ever, need to send SMS's to, but I have done on occasion. My dad is also called Robert, and I text him often. I was getting annoyed because as soon I started typing "Rob...", Robert Aitken was at the top of the list. To solve this, I renamed Robert Aitken's first name in my contacts to "Bob" (since that's what he calls himself anyway). However when I start a new SMS and type "Rob..." as the recipient, it STILL finds "Bob Aitken", despite the letters "Rob" not being associated at all with his contact entry. Is the iPhone simply remembering my history, or is it a neat iOS trick that can associate shortened forms of names with their long form (Bob/Robert, etc)?
