I haven't used iOS 6, but haven't seen this discussed. I think it would be EXTREMELY useful to be able to put several pins for different locations on a map at once. For example, if I wanted to see where 3 different locations are in relation to distance from each other, I could put 3 different pins on the map (1 for a bar, another for a restaurant and another for a friend's house.) I know if you type in "McDonalds" multiple pins show up for different McDonalds restaurants, but I would want different locations. I'm guessing it can't be done though.
