Reminders And Geofencing
One of the newest and niftiest things in iOS 6 is geofencing, which is the ability of iPhone to execute specific events when you cross a specific geographic threshold or location. Geofencing prompts your iPhone to do one thing when you arrive at a specific place and do something different when you leave. This is especially helpful for Reminders. For example, I created a Reminder to have my iPhone tell me to buy a gallon of milk and coffee after I left the train station near my home, so I could pick them up before I got home for the evening.
